Closes #21534

While investigating the panic, I noticed that the code was pretty
complicated and decided to refactor parts of it to reduce redundancy.

Release Notes:

- Fixed an issue where the app could crash when opening the markdown
preview with a malformed image tag

Due to filtering after enumeration, initial candidate ids are assigned
incorrectly. This later causes the wrong item to be picked up when
accessed via index in the vector.

Cherry-picked Fix snippet completion will be trigger, when certain
symbols are pressed (#21578)

Closes #21576

This issue is caused by the fuzzy matching for snippets I added
[here](https://github.com/zed-industries/zed/pull/21524). When
encountering symbols such as `:`, `(`, `.`, etc., the `last_word`
becomes empty, which results in an empty string being passed to
`fuzzy_match`, leading to the return of all templates.

This fix adds an early return when `last_word` is empty.

Closes #21439

This PR uses fuzzy matching for snippet completions instead of
fixed-prefix matching. This mimics the behavior of VSCode.

- Improved suggestions for snippets.

Closes #19054

Rename `max_buffer_row()` to `widest_line_number()` to (hopefully)
prevent
people assuming it means the same as `max_point().row`.

Release Notes:

- Fixed a panic when folding in a multibuffer

This can call back into the app, so must be done when the platform lock
is not
held.

Release Notes:

- Fixes a (rare) panic when changing tab

Closes #4642 

- Added the ability to switch to helix normal mode, with an additional
helix visual mode.
- <kbd>ctrl</kbd><kbd>h</kbd> from Insert mode goes to Helix Normal
mode. <kbd> i </kbd> and <kbd> a </kbd> to go back.
- Need to find a way to perform the helix normal mode selection with
<kbd> w </kbd>, <kbd>e </kbd>, <kbd> b </kbd> as a first step. Need to
figure out how the mode will interoperate with the VIM mode as the new
additions are in the same crate.

Related to #19424

This uses the new text object support, so will only work for languages
that have `textobjects.scm`. It does not integrate with
indentation-based folding for now, and the syntax-based folds don't have
matching fold markers in the gutter (unless they are folded).

Release Notes:

- Add an editor action to fold all function bodies

When searching within a single buffer, activating a search result causes
any fold containing the result to be unfolded. However, this didn't
happen when jumping to a search result from a project-wide search
multibuffer. This PR fixes that.

- Fixed folds not opening when jumping from search results multibuffer

This conflicts with the macOS `ctrl-fn-left/right` bindings for moving
windows around (new in Sequoia).

If you want these use:
```
  {
    "context": "Editor",
    "bindings": {

      "ctrl-end": "editor::MoveToEnd"

In #20742 we added a call to remove_item that retain an item index over
an
await point. This led to a race condition that could panic if another
tab was
removed during that time. (cc @mgsloan)

This changes the API to make it harder to misuse.

Release Notes:

- Fixed a panic when closing tabs containing new unsaved files

Closes #14961

Release Notes:

- Fixed a panic when backspacing at the start of a buffer with
`always_treat_brackets_as_autoclosed` enabled.

It took me a couple of minutes of staring at this speaker icon to figure

This was an oversight in the original PR, dependency-review-action won't
work properly for `push` events

This PR adds GitHub's dependency review action to CI, to flag PRs that
introduce new Cargo.lock entries for vulnerable crates according to the
GHSA database.

An alternative would be to run `cargo audit`, which checks against the
RustSec database. The state of synchronization between these two
databases seems a bit messy, but as far as I can tell GHSA has most
recent RustSec advisories on file, while RustSec is missing a larger
number of recent GHSA advisories.

The dependency review action should be smart enough not to flag PRs
because an untouched entry in Cargo.lock has a new advisory.

I've turned off the "license check" functionality since we have a
separate CI step for that.

Release Notes:

Found this while looking into adding support for the Surface primitive

expensive to compare images for equality. `Eq` and `PartialEq` were

Assistant new chat icon is slightly larger than editor pane new icon.

Adds `IconSize::Small` to assistant default size new chat icon, not
really noticeable, but matches the new icon in editor pane, and the
assistant dropdown menu that have icon size small.
