Solves an issue where Google APIs refuse all requests with file-based
tool calls attached.
This seems to get triggered in the case where:

- copy_path + another file-based tool call is enabled
- default terminal is `/bin/bash` or something similar

It is unclear why this is happening, but removing the terminal commands
in those tool calls seems to have solved the issue.

Closes #37180 and #37414

Release Notes:

- agent: Fix Gemini refusing requests with certain profiles/systems.

## Problem

Zed was crashing with a UTF-8 character boundary error when rendering
text containing multi-byte characters (like emojis or CJK characters):

```
Thread "main" panicked with "byte index 49 is not a char boundary; it is inside '…' (bytes 48..51)"
```

## Root Cause Analysis

The PR reviewer correctly identified that the issue was not in the
DirectWrite boundary handling, but rather in the text run length
calculation in the text system. When text runs are split across lines in
`text_system.rs:426`, the calculation:

```rust
let run_len_within_line = cmp::min(line_end, run_start + run.len) - run_start;
```

This could result in `run_len_within_line` values that don't respect
UTF-8 character boundaries, especially when multi-byte characters (like
'…' which is 3 bytes) get split across lines. The resulting `FontRun`
objects would have lengths that don't align with character boundaries,
causing the panic when DirectWrite tries to slice the string.

## Solution

Fixed the issue by adding UTF-8 character boundary validation in the
text system where run lengths are calculated. The fix ensures that when
text runs are split across lines, the split always occurs at valid UTF-8
character boundaries:

```rust
// Ensure the run length respects UTF-8 character boundaries
if run_len_within_line > 0 {
    let text_slice = &line_text[run_start - line_start..];
    if run_len_within_line < text_slice.len() && !text_slice.is_char_boundary(run_len_within_line) {
        // Find the previous character boundary using efficient bit-level checking
        // UTF-8 characters are at most 4 bytes, so we only need to check up to 3 bytes back
        let lower_bound = run_len_within_line.saturating_sub(3);
        let search_range = &text_slice.as_bytes()[lower_bound..=run_len_within_line];
        
        // SAFETY: A valid character boundary must exist in this range because:
        // 1. run_len_within_line is a valid position in the string slice
        // 2. UTF-8 characters are at most 4 bytes, so some boundary exists in [run_len_within_line-3..=run_len_within_line]
        let pos_from_lower = unsafe {
            search_range
                .iter()
                .rposition(|&b| (b as i8) >= -0x40)
                .unwrap_unchecked()
        };
        
        run_len_within_line = lower_bound + pos_from_lower;
    }
}
```

## Testing

- ✅ Builds successfully on all platforms
- ✅ Eliminates UTF-8 character boundary panics
- ✅ Maintains existing functionality for all text types
- ✅ Handles edge cases like very long multi-byte characters

## Benefits

1. **Root cause fix**: Addresses the issue at the source rather than
treating symptoms
2. **Performance optimal**: Uses the same efficient algorithm as the
standard library
3. **Minimal changes**: Only modifies the specific problematic code path
4. **Future compatible**: Can be easily replaced with
`str::floor_char_boundary()` when stabilized

## Alternative Approaches Considered

1. **DirectWrite boundary fixing**: Initially tried to fix in
DirectWrite, but this was treating symptoms rather than the root cause
2. **Helper function approach**: Considered extracting to a helper
function, but inlined implementation is more appropriate for this
specific use case
3. **Standard library methods**: `floor_char_boundary()` is not yet
stable, so implemented equivalent logic

The chosen approach provides the best balance of performance, safety,
and code maintainability.

### Summary

This PR fixes the way `go test` commands are generated for **testify
suite test methods**.
Previously, only the method name was included in the `-run` flag, which
caused Go’s test runner to fail to find suite test cases.

---

### Problem


https://github.com/user-attachments/assets/e6f80a77-bcf3-457c-8bfb-a7286d44ff71

1. **Incorrect command** was generated for suite tests:

   ```bash
   go test -run TestSomething_Success
   ```

   This results in:

   ```
   testing: warning: no tests to run
   ```

2. The correct format requires the **suite name + method name**:

   ```bash
   go test -run ^TestFooSuite$/TestSomething_Success$
   ```

Without the suite prefix (`TestFooSuite`), Go cannot locate test methods
defined on a suite struct.

---

### Changes Made

* **Updated `runnables.scm`**:

  * Added a new query rule for suite methods (`.*Suite` receiver types).
* Ensures only methods on suite structs (e.g., `FooSuite`) are matched.
  * Tagged these with `go-testify-suite` in addition to `go-test`.

* **Extended task template generation**:

  * Introduced `GO_SUITE_NAME_TASK_VARIABLE` to capture the suite name.
  * Create a `TaskTemplate` for the testify suite.

* **Improved labeling**:

* Labels now show the full path (`go test ./pkg -v -run
TestFooSuite/TestSomething_Success`) for clarity.

* **Added a test** `test_testify_suite_detection`:

* Covered testify suite cases to ensure correct detection and command
generation.

---

### Impact


https://github.com/user-attachments/assets/ef509183-534a-4aa4-9dc7-01402ac32260

* **Before**: Running a suite test method produced “no tests to run.”
* **After**: Suite test methods are runnable individually with the
correct `-run` command, and full suites can still be executed as before.

### Release Notes

* Fixed generation of `go test` commands for **testify suite test
methods**.
Suite methods now include both the suite name and the method name in the
`-run` flag (e.g., `^TestFooSuite$/TestSomething_Success$`), ensuring
they are properly detected and runnable individually.

Buffer search initiates a new search every time a key is pressed in the
buffer search bar. This would cancel the task associated with any
pending searches. Whenever one of these searches was canceled Zed would
log `[search]: oneshot canceled`. This log would trigger almost on every
keypress when typing moderately fast. This PR silences these logs by not
treating canceled searches as errors.

I noticed that after we paste in line mode, the cursor position is

This took me quite a while to find out when I developed my first
language extension. I had non-matching entries in the `languages` array
and in the name field of `config.toml`, and it was especially tricky
because the zed extension would start up, but not the language server. I
sure which this had been in the docs, so I am contributing it now!

In particular,
* if the selection ends at the beginning of the next line, and the
current line under the cursor is empty, we paste at the selection's end.
* if however the current line under the cursor is empty, we need to move
to the beginning of the next line to avoid pasting above the end of
current selection

In addition, in line mode, we always move the cursor to the end of the
inserted text. Otherwise, while it looks fine visually,
inserting/appending ends up in the next logical line which is not
desirable.

Closes #38495

Cause:

- When the Find input is focused, CopyPath/CopyRelativePath were handled
by the editor and stopped during the bubble phase, preventing
BufferSearchBar from relaying to the file-backed editor.

Release Notes:

- Fixes “Workspace: Copy Relative Path” not copying while the Find bar
is focused.

This PR adds automatic markdown URL embedding on paste when you are in
text associated with the Markdown language and you have a valid URL in
your clipboard. This the default behavior in VS Code and GitHub, when
pasting a URL in Markdown. It works in both singleton buffers and multi
buffers.

One thing that is a bit unfortunate is that, previously, `do_paste` use
to simply call `Editor::insert()`, in the case of pasting content that
was copied from an external application, and now, we are duplicating
some of `insert()`'s logic in place, in order to have control over
transforming the edits before they are inserted.

Release Notes:

- Added automatic Markdown URL embedding on paste.

Vim mode currently supports `gt` (go to next tab) and `gT` (go to
previous tab) but not with count. Implement the expected behavior as
defined by vim:

- `<count>gt` moves to tab `<count>`
- `<count>gT` moves to previous tab `<count>` times (with wraparound)

Release Notes:

- Improved vim `gt` and `gT` to support count, e.g. `5gt` - go to tab 5,
`8gT` - go to 8th previous tab with wraparound.

It requires the agent to implement the (still unstable) model selection
API. Will allow us to test it out before stabilizing.

This button already exists in the main menu, as well as the "New
Session" view in the debugger panel. However, this view disappears after
starting the debugging session. This PR adds the same button to the
debugger control strip that remains accessible. This is convenient for
people editing their debug.json frequently.

Site-node: I feel like the `Cog` icon would be more appropriate, but I
picked `Code` to stay consistent with the "New Session" view.

Add an auto-profiler for our tests, to hopefully allow better triage of
performance impacts resulting from code changes. Comprehensive usage
docs are in the code.

Currently, it uses hyperfine under the hood and prints markdown to the
command line for all crates with relevant tests enabled. We may want to
expand this to allow outputting json in the future to allow e.g.
automatically comparing the difference between two runs on different
commits, and in general a lot of functionality could be added (maybe
measuring memory usage?).

It's enabled (mostly as an example) on two tests inside `gpui` and a
bunch of those inside `vim`. I'd have happily used `cargo bench`, but that's nightly-only.
