This PR adds new granular tokens per minute columns to the `models`
table in preparation for more fine-grained rate limits.

The following columns have been added:

- `max_input_tokens_per_minute`
- `max_output_tokens_per_minute`

These mirror the "Maximum input tokens per minute (ITPM)" and "Maximum
output tokens per minute (OTPM)" [rate limits from
Anthropic](https://docs.anthropic.com/en/api/rate-limits#rate-limits).

Use the `NSOperatingSystemVersion` struct provided by the cocoa crate
instead of our own. Additionally we can directly use
`isOperatingSystemAtLeastVersion` instead of manually implementing
version comparison logic.

The `isOperatingSystemAtLeastVersion` instance method has been available
since MacOS 10.10, which released a decade ago.

Documentation for `isOperatingSystemAtLeastVersion `:

Changes default keymaps to more closely match the behavior of VSCode.

New Zed behavior:
`cmd-k w` / `ctrl-k w` -- Closes all buffers in the current pane
`cmd-k cmd-w` / `ctrl-k ctrl-w` -- Closes all buffers in all panes

VScode:
`cmd-k cmd-w` is workbench.action.closeAllEditors (close all buffers in
all splits)
`cmd-k w` is workbench.action.closeEditorsInGroup (close all buffers in
current split)

Both leave pinned tabs untouched.

Release Notes:

- Improved keybindings for close all tabs to better match VSCode
behavior

Release Notes:

- Fixed a bug that would prevent rejecting certain agent edits.

This is a follow up to https://github.com/zed-industries/zed/pull/14821,
which escaped `$` but not `^`.

This is fine for `bash`, but causes issues with `zsh`. This change
escapes the `^`. I tested this against `bash`, `zsh` and `fish`

I suspect such escaping would probably need to be done at some
shell-specific layer of the code, but for now it seems like the tasks
provided by the `ContextProvider` are supposed to be shell agnostic.

To reproduce the original issue:
1. Create a Go test file in a module that just contains a single test
`TestABC`.
2. Run `zsh -i -c "go test -run ^TestABC\$"` which is what Zed tries to
run when the task for a specific Go test is executed.
3. An error that there are no tests to run will be produced even though
there is a test.
4. Run `zsh -i -c "go test -run \^TestABC\$"` (note the backslash before
^).
5. The test will run successfully.

Example:
``` go
package bar

import "testing"

func TestABC(t *testing.T) {}
```

Release Notes:

- fix: Escape the ^ in the Go test -run regex to improve shell
compatibility (notably with zsh).

This makes sure that we specify which lines the agent actually read,
avoids confusing scenarios such as:

<img width="642" alt="Screenshot 2025-04-04 at 10 22 10"
src="https://github.com/user-attachments/assets/2680c313-4f77-4971-8743-8e3f5327c18d"
/>

Here the agent starts out by actually only reading a certain amount of
lines when the first tool call happens, then it does a second tool call
to read the whole file. To the user this looks like to identical tool
calls.

Now:

With the recent deprecation of `rustPlatform.fetchCargoTarball` +
migration to using `fetchCargoVendor` by default in `buildRustPackage`
(NixOS/nixpkgs#394012), the `cargo-bundle` override strategy used here,
as prescribed by the
[nixos asia wiki](https://nixos.asia/en/buildRustPackage) no longer
works:

https://github.com/zed-industries/zed/blob/c6e2d20a02b523172aea8a22fa2ec6c8975b52e4/nix/build.nix#L100-L116

[`fetchCargoTarball` produced a single derivation][tarball-drv] but
`fetchCargoVendor` [produces two][vendor-drvs]:
  - `${name}-vendor-staging` (inner; FoD)
  - `${name}-vendor` (outer)

[tarball-drv]:
https://github.com/NixOS/nixpkgs/blob/36fd87baa9083f34f7f5027900b62ee6d09b1f2f/pkgs/build-support/rust/fetch-cargo-tarball/default.nix#L79
[vendor-drvs]:
https://github.com/NixOS/nixpkgs/blob/10214747f5e6e7cb5b9bdf9e018a3c7b3032f5af/pkgs/build-support/rust/fetch-cargo-vendor.nix#L52-L103

`overrideAttrs` here is setting `outputHash` on the latter (which isn't
a fixed-output-derivation and does not have `outputHashMode` set which
implies `outputHashMode = "flat"`) instead of the inner; this results in
errors like this:
```console
❯ nix develop
error: output path '/nix/store/cb57w05zvsqxshqjl789kmsy9pbqjn06-cargo-bundle-0.6.1-zed-vendor.tar.gz' should be a non-executable regular file since recursive hashing is not enabled (outputHashMode=flat)
error: 1 dependencies of derivation '/nix/store/k3azmxljgjn26hqyhg9m1y3lhx32y939-cargo-bundle-0.6.1-zed.drv' failed to build
error: 1 dependencies of derivation '/nix/store/8ag4v0m90m4kcaq1ypp7f85pp8s6fxgc-nix-shell-env.drv' failed to build
```

> [!NOTE]
> you will need to remove
`/nix/store/cb57w05zvsqxshqjl789kmsy9pbqjn06-cargo-bundle-0.6.1-zed-vendor.tar.gz`
> from your nix store in order to be able to reproduce this

We want to be setting `outputHash` on the [first derivation][first-drv]
instead. This change has us just do the call to `fetchCargoTarball`
manually instead of using overrides.

[first-drv]:
https://github.com/NixOS/nixpkgs/blob/10214747f5e6e7cb5b9bdf9e018a3c7b3032f5af/pkgs/build-support/rust/fetch-cargo-vendor.nix#L85

---

I suspect CI/other machines didn't catch this due to a store path
matching the name + `outputHash` already being present but I'm not
entirely sure how this happened...

`sha256-Q49FnXNHWhvbH1LtMUpXFcvGKu9VHwqOXXd+MjswO64=` is actually a
`fetchCargoTarball` hash, not a `fetchCargoVendor` hash (and upstream
`cargo-about`'s `cargoDeps` [has been using `cargoVendor`][ups] since
before the nixpkgs bump in 50ad71a6306b45926091b8e37036ea8fe237f299)

Previously, when comparing a block with an empty range to an empty query
range in non-inclusive mode, our binary search logic could end up
computing an inverted range, causing a panic.

This commit adds special casing when comparing empty blocks with empty
ranges.

cc @as-cii: I'm realizing that the approach to searching for the
intersecting replacement blocks makes some invalid assumptions about the
ordering of replace decorations. They aren't ordered at all by their end
range. @maxbrunsfeld and I are wondering if long term, we should remove
replace decorations and find another solution for folding buffers in
multi buffers.

Release Notes:

- Fixed an occasional panic that would occur when navigating to the next

This PR adds a check to avoid dereferencing a null pointer in
`MacWindow::active_window`.

Rust 1.86 now has a [debug assertion for dereferencing null
pointers](https://blog.rust-lang.org/2025/04/03/Rust-1.86.0.html#debug-assertions-that-pointers-are-non-null-when-required-for-soundness),
which means that losing focus of the window would cause a null pointer
to be dereferenced and panic.

This PR disables `parallel_tool_calls` for the models that support it,
as the Agent currently expects at most one tool use per turn.

model that doesn't support it.

This makes context essentially work the same way as `read-file`,
increasing the likelihood of cache hits.

Just like with `read-file`, we'll notify the model when the user makes
an edit to one of the tracked files. In the future, we want to send a
diff instead of just a list of files, but that's an orthogonal change.

### Context 

The Anthropic API fails if a request message contains a tool use and no
`Text` segments or it only contains empty `Text` segments. These are
cases that the model itself produces, but the API doesn't support
sending them back.

#27917 fixed this by appending "Using tool..." in the thread's message,
but this causes the actual conversation to include it, so it would
appear in the UI (we would actually display a gap because we never
rendered its markdown, but "Using tool..." would show up when the thread
was restored).

### Solution

We'll now only append this placeholder when we build the request, so the
API still sees it, but the UI/Thread doesn't.

Another issue we found is that the model starts mimicking these
placeholders in later tool uses which is undesirable. So unfortunately,
we had to add logic to filter them out.

Release Notes:

- agent: Improved rendering of tool uses without text

Closes #28002

This PR updates the `runnabless.scm` for Rust to improve detection of
test modules with non-standard names. Instead of matching on the module
name, we now check for the `#[cfg(test)]`-attribute above test modules.
This allows for generic matching whilst not regressing the previous
behaviour.

Release Notes:

- Fixed an issue where the thinking step would show up as pending even
when the generation was cancelled

This happened because of two reasons:

- `Workspace::recent_navigation_history` didn't include the current file
- The context picker added the current file to a exclude list

The latter was actually intentional because we already show the file in
the suggested context, but now that we actually have mentions, it's just
inconvenient not to have it there.

This PR resolves a small regression introduced by the
debugger-introduction, which causes the active line number to no longer
be highlighted in the gutter as long as it is not part of a selection. A
user reported this issue [on
Discord](https://discord.com/channels/869392257814519848/995403703894954060/1357153291913662567).

Prior to the debugger-commit, an active line number was highlighted if
it was part of the editor active line numbers:

https://github.com/zed-industries/zed/blob/ed4e654fdf66fb886414198ac6db1a2f24d729a5/crates/editor/src/element.rs#L4295-L4303

With the debugger-introduction, the code was changed to only highlight
lines which are part of a selection:

https://github.com/zed-industries/zed/blob/e2aaf9b7046dd8d8430ff82554fe13d69431e443/crates/editor/src/element.rs#L2411-L2422

However, the check whether it is within a selection is not neccesary, as
the line is an active line as long as it is within the map of active
lines.

This PR restores the previous behavior.

https://github.com/zed-industries/zed/pull/26454 In this PR, we
separated painting for text line into two parts: `paint` and
`paint_background`. This allows selections to appear in front of the
text background but behind the text itself in the editor.

The `paint_background` method was implemented for `ShapedLine` but not
for `WrappedLine`. This PR adds that, fixing the background rendering
for inline code blocks in Markdown, as they use `WrappedLine`.

Closes #27769

When adding snippet we were not respecting autoclose setting, before
creating AutocloseRegion. This leads to cursor to skip over instead of
typing that character. This PR fixes it.

Release Notes:

- Fixed certain case where typing closing bracket would skip it when
auto close setting is turned off.

This adds a "workspace-hack" crate, see
[mozilla's](https://hg.mozilla.org/mozilla-central/file/3a265fdc9f33e5946f0ca0a04af73acd7e6d1a39/build/workspace-hack/Cargo.toml#l7)
for a concise explanation of why this is useful. For us in practice this
means that if I were to run all the tests (`cargo nextest r
--workspace`) and then `cargo r`, all the deps from the previous cargo
command will be reused. Before this PR it would rebuild many deps due to
resolving different sets of features for them. For me this frequently
caused long rebuilds when things "should" already be cached.

To avoid manually maintaining our workspace-hack crate, we will use
[cargo hakari](https://docs.rs/cargo-hakari) to update the build files
when there's a necessary change. I've added a step to CI that checks
whether the workspace-hack crate is up to date, and instructs you to
re-run `script/update-workspace-hack` when it fails.

Finally, to make sure that people can still depend on crates in our
workspace without pulling in all the workspace deps, we use a `[patch]`
section following [hakari's
instructions](https://docs.rs/cargo-hakari/0.9.36/cargo_hakari/patch_directive/index.html)

One possible followup task would be making guppy use our
`rust-toolchain.toml` instead of having to duplicate that list in its
config, I opened an issue for that upstream: guppy-rs/guppy#481.

TODO:
- [x] Fix the extension test failure
- [x] Ensure the dev dependencies aren't being unified by Hakari into
the main dependencies
- [x] Ensure that the remote-server binary continues to not depend on
LibSSL
