Vim visual mode and Helix selection mode both require the cursor to be
on the last character of the selection. Until now, this was implemented
by offsetting the cursor one character to the left whenever a block
cursor is used. (Since the visual modes use a block cursor.)

However, this oversees the problem that **some users might want to use
the block cursor without being in visual mode**. Meaning that the cursor
is offset by one character to the left even though Vim/Helix mode isn't
even activated.

Since the Vim mode implementation is separate from the `editor` crate
the solution is not as straightforward as just checking the current vim
mode. Therefore this PR introduces a new `Editor` struct field called
`cursor_offset_on_selection`. This field replaces the previous check 
condition and is set to `true` whenever the Vim mode is changed to a 
visual mode, and `false` otherwise.

Closes #36677 and #20121

Release Notes:

- Fixes block and hollow cursor being offset when selecting text

Release Notes:

- Make Helix keybinds use visual line movement for `j`, `Down`, `k` and `Up`, and textual line movement for `g j`, `g Down`, `g k` and `g Up`.

For folders and files basically any selected item in the git panel we
draw a border around it. The issue is that the right side of this border
wasn't ever visible.

In the project_panel.rs file I've saw that the decision was to make the
right side border 2 pixels. And this panel doesn't have this issue, no
matter which side of the dock is selected. So it was a very easy `look
at how we did x do y`.

The issue is that we aren't consistent in using the same
`panel_focus_border` color across zed.
Might completely fix my issue: #44750 

For focused items in: 
- outline panel
- git panel

While these: 
- project panel
- keymap editor tab

Are actually using the panel_focused_border option. 

Not sure if this warrants a release note, feel free to adapt.

This PR makes zed terminal gruvbox theme consistent with other terminals
themes.
Current ansi colors is broken, by not only not using colors from
original palette, but also by inverting of bright/normal colors...

Currently I took colors from Ghostty (Iterm2 themes), making sure that
they are consistent with palette.
For dim colors I darken them by decreasing "Value" from HSV
representation of colors by 30%.

I am open to discussion and willing to implement those changes for light
theme after receiving feedback.

Examples below:

I have noticed you care about `SumTree` (and `Rope`) construction
performance, hence using rayon for parallelism and careful `Chunk`
splitting to avoid reallocation in `Rope::push`. It seemed strange to me
that using multi-threading is that beneficial there, so I tried to
investigate why the serial version (`SumTree::from_iter`) is slow in the
first place.

From my analysis I believe there are two main factors here:
1. `SumTree::from_iter` stores temporary `Node<T>` values in a vector
instead of heap-allocating them immediately and storing `SumTree<T>`
directly, as `SumTree::from_par_iter` does.
2. `Chunk::new` is quite slow: for some reason the compiler does not
vectorize it and seems to struggle to optimize u128 shifts (at least on
x86_64).

For (1) the solution is simple: allocate `Node<T>` immediately after
construction, just like `SumTree::from_par_iter`.
For (2) I was able to get better codegen by rewriting it into a simpler
per-byte loop and splitting computation into smaller chunks to avoid
slow u128 shifts.

There was a similar effort recently in #43193 using portable_simd
(currently nightly only) to optimize `Chunk::push_str`. From what I
understand from that discussion, you seem okay with hand-rolled SIMD for
specific architectures. If so, then I also provide sse2 implementation
for x86_64. Feel free to remove it if you think this is unnecessary.

To test performance I used a big CSV file (~1GB, mostly ASCII) and
measured `Rope::from` with this program:
```rust
fn main() {
    let text = std::fs::read_to_string("big.csv").unwrap();
    let start = std::time::Instant::now();
    let rope = rope::Rope::from(text);
    println!("{}ms, {}", start.elapsed().as_millis(), rope.len());
}
```

Here are results on my machine (Ryzen 7 4800H)

|              | Parallel | Serial |
| ------------ | -------- | ------ |
| Before       | 1123ms   | 9154ms |
| After        | 497ms    | 2081ms |
| After (sse2) | 480ms    | 1454ms |

Since serial performance is now much closer to parallel, I also
increased `PARALLEL_THRESHOLD` to 1000. In my tests the parallel version
starts to beat serial at around 150 KB strings. This constant might
require more tweaking and testing though, especially on ARM64.

## Fix incorrect directory path folding in slash command file collection

**Description:**
This PR fixes a bug in the `collect_files` function where the directory
folding logic (used to compact chains like `.github/workflows`) failed
to reset its state when traversing out of a folded branch.

**The Issue:**
The `folded_directory_names` accumulator was persisting across loop
iterations. If the traversal moved from a folded directory (e.g.,
`.github/workflows`) to a sibling directory (e.g., `.zed`), the sibling
would incorrectly inherit the prefix of the previously folded path,
resulting in incorrect paths like `.github/.zed`.

**The Fix:**
* Introduced `folded_directory_path` to track the specific path
currently being folded.
* Added a check to reset `folded_directory_names` whenever the traversal
encounters an entry that is not a child of the currently folded path.
* Ensured state is cleared immediately after a folded directory is
rendered.

**Release Notes:**
- Fixed an issue where using slash commands to collect files would
sometimes display incorrect directory paths (e.g., showing
`.github/.zed` instead of `.zed`) when adjacent directories were
automatically folded.

### Summary:
- Ensure the external agents with ACP servers start via non-interactive
shells to prevent shell startup noise from corrupting JSON-RPC.
- Apply the same tweak to MCP stdio transports so remote context servers
aren’t affected by prompts or greetings.

### Description:
Switch both ACP and MCP stdio launch paths to call
`ShellBuilder::non_interactive()` before building the command. This
removes `-i` on POSIX shells, suppressing prompt/title sequences that
previously prefixed the first JSON line and caused `serde_json` parse
failures. No functional regressions are expected: both code paths only
need a shell for Windows/npm script compatibility, not for
interactivity.

Release Notes:
- Fixed external agents that hung on “Loading…” when shell startup
output broke JSON-RPC initialization.

Zed currently doesn’t support all protocol extensions implemented by
`clangd`, but it does support two:

- `textDocument/inactiveRegion`
- `textDocument/switchSourceHeader`

Closes https://github.com/zed-industries/zed/issues/39189

Release Notes:

- Fixed terminal hyperlinking not working for `file://` schemes with
windows drive letters

Fixes #33958

## Problem

When opening a terminal in Zed, `SHLVL` incorrectly starts at 2 instead
of 1. On `workspace: reload`, it increases by 2 instead of 1.

## Root Cause

1. Zed's `shell_env::capture()` spawns a login shell (`-l -i -c`) to
capture the user's environment, which increments `SHLVL`
2. The captured `SHLVL` is passed through to the PTY options
3. When alacritty_terminal spawns the user's shell, it increments
`SHLVL` again

Result: `SHLVL` = captured value + 1 = 2 (when launched from Finder)

## Solution

Remove `SHLVL` from the environment in `TerminalBuilder::new()` before
passing it to alacritty_terminal. This allows the spawned shell to
initialize `SHLVL` to 1 on its own, matching the behavior of standalone
terminal emulators like iTerm2, Kitty, and Alacritty.

## Testing

- Launch Zed from Finder → open terminal → `echo $SHLVL` → should output
`1`
- Launch Zed from shell → open terminal → `echo $SHLVL` → should output
`1`
- `workspace: reload` → open terminal → `echo $SHLVL` → should remain
`1`
- Tested with bash, zsh, fish

Release Notes:

- Fixed terminal `$SHLVL` starting at 2 instead of 1
([#33958](https://github.com/zed-industries/zed/issues/33958))

Also factor out some common code in the evals.

This PR adds a staff-only button to the edit prediction menu for
capturing your current editing session as edit prediction example file.

When you click that button, it opens a markdown tab with the example. By
default, the most recent change that you've made is used as the expected
patch, and all of the previous events are used as the editing history.

Imitating the approach of #41829. Prevents e.g. reverting a hunk and
having that excerpt yanked out from under the cursor.

Release Notes:

- git: Improved stability of excerpts when editing in the project diff.

The test `test_collaborating_with_completion` has a latent race
condition that hasn't manifested on CI yet but could cause hangs with
certain task orderings.

## The Bug

Commit `fd1494c31a` set up LSP request handlers AFTER typing the trigger
character:

```rust
// Type trigger first - spawns async tasks to send completion request
editor_b.update_in(cx_b, |editor, window, cx| {
    editor.handle_input(".", window, cx);
});

// THEN set up handlers (race condition!)
fake_language_server
    .set_request_handler::<lsp::request::Completion, _, _>(...)
    .next().await.unwrap();  // Waits for handler to receive a request
```

Whether this works depends on task scheduling order, which varies by
seed. If the completion request is processed before the handler is
registered, the request goes to `on_unhandled_notification` which claims
to handle it but sends no response, causing a hang.

## Changes

- Move handler setup BEFORE typing the trigger character
- Make `TestDispatcher::spawn_realtime` panic to prevent future
non-determinism from real OS threads
- Add `execution_hash()` and `execution_count()` to TestDispatcher for
debugging
- Add `DEBUG_SCHEDULER=1` logging for task execution tracing
- Document the investigation in `situation.md`

This adds implementations of `std::iter::Sum` for `Pixels`, allowing the
use of `.sum()` on iterators of `Pixels` values.

### Changes
- Implement `Sum<Pixels>` for `Pixels` (owned values)
- Implement `Sum<&Pixels>` for `Pixels` (references)

This enables ergonomic patterns like:
```rust
let total: Pixels = pixel_values.iter().sum();
```

This change matches how normal hovers are handled (which early return
with `None` in this branch)

Fix a bug where the branch picker would be dismissed before completing
the add remote flow, thus making Zed unable to add remote repositories
through the branch picker.

This bug was caused by the picker always being dismissed on the confirm
action, so the fix was stopping the branch modal from being dismissed
too early.

I also cleaned up the UI a bit and code.

1. Removed the loading field from the Branch delegate because it was
never used and the activity indicator will show remote add command if it
takes a while.
2. I replaced some async task spawning with the use of `cx.defer`.
3. Added a `add remote name` fake entry when the picker is in the name
remote state. I did this so the UI would be consistent with the other
states.
4. Added two regression tests. 
4.1 One to prevent this bug from occurring again:
https://github.com/zed-industries/zed/pull/44742
4.2 Another to prevent the early dismissal bug from occurring 
5. Made `init_branch_list_test` param order consistent with Zed's code
base

We were panicking whenever something went wrong with an example in the
CLI. This can be very disruptive when running many examples, and e.g a
single request fails. Instead, if running more than one example, errors
will now be logged alongside instructions to explore and re-run the
example by itself.
