Cherry-picked Revert "Avoid endless loop of the diagnostic updates
(#21209)" (#21764)

This reverts commit 9999c31859210654dd572d54dfa42b67c00b33b0.

Release Notes:

- Fixes diagnostics not updating in some circumstances

Some of our users ran into a peculiar bug: autoimports with vtsls were
leaving behind an extra curly brace. I think we were slightly incorrect
in always requesting a follow-up completion without regard for last
result of completion request (whether it was incomplete or not).
Specifically, we're falling into this branch in current form:
https://github.com/yioneko/vtsls/blob/037c2b615bf4cfe9dd65d9affc7a155fbb2ca255/packages/service/src/service/completion.ts#L121
which then leads to incorrect edits being returned from vtsls.

Release Notes:

- Fixed an edge case with appliance of autocompletions in VTSLS that
could result in incorrect edits being applied.

Closes https://github.com/zed-industries/zed/issues/21652

* prevents zooming out the panel when any terminal pane is closed
* forces focus on new terminal panes, to prevent the workspace from
getting odd pane events in the background

Release Notes:

- (Preview only) Fixed zoomed terminal pane issues on split

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.

Release Notes:

- Fixed folds not opening when jumping from search results multibuffer

openbsd-netcat is required for interactive SSH Remoting prompts
(password, passphrase, 2fa, etc).

This reverts commit 614b3b979b7373aaa6dee84dfbc824fce1a86ea8.

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-home": "editor::MoveToBeginning",
      "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
out it was a speaker! I even researched whether the `.wav` file type had
a specific icon, given I thought it was a specific triangle of sorts 😅
I'm sensing audio waves, at this size, will be easier to parse.
