This PR prevents any unnecessary lines from being rendered in the edit
file tool card in the case of small diffs.

I think this (hopefully) addresses the last remaining task from
https://github.com/zed-industries/zed/pull/29448.

n the second commit I also preemtively disabled vertical overscrolling
for full mode editors which are sized by content. This is basically the
same fix as in https://github.com/zed-industries/zed/pull/28471.
Strictly speaking, this is not needed for the fix here, but I thought it
might be nice to have for the future to prevent any issues from occuring
due to overscroll.

Release Notes:

- agent: Improved rendering of small diffs for the edit file tool card.

plan.

Mostly somewhat small UI tweaks around the MCP extension config flow and

Release Notes:

This pull request introduces a new tool for streaming edits. The
short-term goal is for this tool to replace the existing `EditFileTool`,
but we want to get this out the door as soon as possible so that we can
start testing it.

`StreamingEditFileTool` is mutually exclusive with `EditFileTool`. It
will be enabled by default for anyone who has the `agent-stream-edits`
feature flag, as well as people that set `assistant.stream_edits` to
`true` in their settings.

### Implementation

Streaming is achieved by requesting a completion while the `edit_file`
tool gets called. We invoke the model by taking the existing
conversation with the agent and appending a prompt specifically tailored
for editing. In that prompt, we ask the model to produce a stream of
`<old_text>`/`<new_text>` tags. As the model streams text in, we
incrementally parse it and start editing as soon as we can.

### Evals

Note that, as part of this pull request, I also defined some new evals
that I used to drive the behavior of the recursive LLM call. To run
them, use this command:

```bash
cargo test --package=assistant_tools --features eval -- eval_extract_handle_command_output
```

Or comment out the `#[cfg_attr(not(feature = "eval"), ignore)]` macro.

I recommend running them one at a time, because right now we don't
really have a way of orchestrating of all these evals. I think we should
invest into that effort once the new agent panel goes live.

Closes #ISSUE

Release Notes:

- N/A *or* Added/Fixed/Improved ...

Adjusts the way `cargo` and `rust-analyzer` diagnostics are fetched into
Zed.

Nothing is changed for defaults: in this mode, Zed does nothing but
reports file updates, which trigger rust-analyzers'
mechanisms:

* generating internal diagnostics, which it is able to produce on the
fly, without blocking cargo lock.
Unfortunately, there are not that many diagnostics in r-a, and some of
them have false-positives compared to rustc ones

* running `cargo check --workspace --all-targets` on each file save,
taking the cargo lock
For large projects like Zed, this might take a while, reducing the
ability to choose how to work with the project: e.g. it's impossible to
save multiple times without long diagnostics refreshes (may happen
automatically on e.g. focus loss), save the project and run it instantly
without waiting for cargo check to finish, etc.

In addition, it's relatively tricky to reconfigure r-a to run a
different command, with different arguments and maybe different env
vars: that would require a language server restart (and a large project
reindex) and fiddling with multiple JSON fields.

The new mode aims to separate out cargo diagnostics into its own loop so
that all Zed diagnostics features are supported still.


For that, an extra mode was introduced:

```jsonc
"rust": {
  // When enabled, Zed runs `cargo check --message-format=json`-based commands and
  // collect cargo diagnostics instead of rust-analyzer.
  "fetch_cargo_diagnostics": false,
  // A command override for fetching the cargo diagnostics.
  // First argument is the command, followed by the arguments.
  "diagnostics_fetch_command": [
    "cargo",
    "check",
    "--quiet",
    "--workspace",
    "--message-format=json",
    "--all-targets",
    "--keep-going"
  ],
  // Extra environment variables to pass to the diagnostics fetch command.
  "env": {}
}
```

which calls to cargo, parses its output and mixes in with the existing
diagnostics:

Release Notes:

- Added a way to get diagnostics from cargo and rust-analyzer without
mutually locking each other
- Added `ctrl-r` binding to refresh diagnostics in the project
diagnostics editor context

Release Notes:

Closes #28414

Makes it so that `do`, `then`, `done`, `else`, etc are treated as
brackets in bash. They are not auto-closed *yet* as that requires
additional work to function properly, however they can now be toggled
between using `%` in vim. Additionally, newlines are inserted like they
are with regular brackets (`{}()[]""''`) when hitting enter between
them.

While `if <-> fi` `while/for <-> done` and `case <-> esac` are the
*logical* matching pairs, I've opted to instead match between `then <->
else/elif/fi` `do <-> done` and `in <-> esac` as these are the pairs
that delimit the sub-scope, and are more similar to the `{}` style
bracket pairs than `if <-> }` in a c-like syntax. This does cause some
wierd behavior with `else` in `if` expressions as it matches both with
the previous `then` as well as the following `fi`, so in this case

```bash
if true; then
   foo
else
   bar
f|i
```

after hitting `%` twice times (where cursor is `|`), the cursor will end
up on the `then` instead of back on the `fi` as hitting `%` on the else
will *always* navigate up to the `then`

Release Notes:

- vim: Improved behavior around word-based delimiters in bash (`do <->
done`, `then <-> fi`, etc) so they can be toggled between using `%`

This is based on having observed that there is a lot of variation
between runs on `n=1` and `n=3`.

* With `n=8` two runs on the same branch give answers that seem close
enough to be reasonably consistent.
* With higher concurrency, trying to run this many repetitions seems to
lead language servers to time out a lot, causing evals to fail.

Closes #27073

Currently, when searching for a file with Ctrl+P, and the first file
found is the active one, file_finder skips focus to the second file
automatically. This PR adds a setting to disable this and make the first
file always the focused one.

Default setting is still skipping the active file.

Release Notes: 

- Added the `skip_focus_for_active_in_search` setting for the file
finder, which allows turning off the default behavior of skipping focus
on the active file while searching in the file finder.
