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 😅

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.

Ideally, I wouldn't like to have yet another place mapping extensions to

Adds a new "Copy Extension ID" action to the dropdown of remote
extension cards in the extensions list UI. Would have liked for it to be
a context menu where you could click anywhere on the card, but couldn't
figure out how to integrate that with the existing setup.

I've been missing this from VSCode's extension panel, which allows this
on right click:

of not having "Transform" here as that felt it made less sense for
terminal-related prompts, where arguably more frequently, one would be
suggesting for actual commands rather than code transformation.

Closes https://github.com/zed-industries/zed/issues/12029

Allows to introspect project items inside items more deeply, checking
them for being dirty.
For that:
* renames `project::Item` into `project::ProjectItem`
* adds an `is_dirty(&self) -> bool` method to the renamed trait
* changes the closing logic to only care about dirty project items when
checking for save prompts conditions
* save prompts are raised only if the item is singleton without a
project path; or if the item has dirty project items that are not open
elsewhere

Release Notes:

- Fixed item closing overly triggering save dialogues

This addition comes after attempting building Zed from source.

As part of the process, one of the components (a crate I presume) called
`ring` failed to compile due to the following sequence of console
messages:

```log
warning: ring@0.17.8: Compiler family detection failed due to error: ToolNotFound: Failed to find tool. Is `musl-gcc` installed?
warning: ring@0.17.8: Compiler family detection failed due to error: ToolNotFound: Failed to find tool. Is `musl-gcc` installed?

error: failed to run custom build command for `ring v0.17.8`
```

Adding this library should help fix the issue on Fedora 41 at least, and
possibly will help fixing it for other RedHat based distributions as
well.

- Add musl-gcc as dependency

Closes #15788, #13258

This is a long-standing issue with a few previous attempts to fix it,
such as [this one](https://github.com/zed-industries/zed/pull/17496).
However, that fix was later reverted because it resolved the blur issue
but caused a size issue. Currently, both blur and size issues persist
when you set a custom cursor size from GNOME Settings and use fractional
scaling.

This PR addresses both issues.

---

### Context

A new Wayland protocol,
[cursor-shape-v1](https://gitlab.freedesktop.org/wayland/wayland-protocols/-/merge_requests/194),
allows the compositor to handle rendering the cursor at the correct size
and shape. This protocol is implemented by KDE, wlroots (Sway-like
environments), etc. Zed supports this protocol, so there are no issues
on these desktop environments.

However, GNOME has not yet
[adopted](https://gitlab.gnome.org/GNOME/gtk/-/merge_requests/6212) this
protocol. As a result, apps must fall back to manually rendering the
cursor by specifying the theme, size, scale, etc., themselves. Zed also
implements this fallback but does not correctly account for the display
scale.

---

### Scale Fix

For example, if your cursor size is `64px` and you’re using fractional
scaling (e.g., `150%`), the display scale reported by the window query
will be an integer value, `2` in this case. Why `2` if the scale is
`150%`? That’s what the new protocol aims to improve. However, since
GNOME Wayland uses this integer scale everywhere, it’s sufficient for
our use case.

To fix the issue, we set the `buffer_scale` to this value. But that
alone doesn’t solve the problem. We also need to generate a matching
theme cursor size for this scaled version. This can be calculated as
`64px` * `2`, resulting in `128px` as the theme cursor size.

---

### Size Fix

The XDG Desktop Portal’s `cursor-size` event fails to read the cursor
size because it expects an `i32` but encounters a type error with `u32`.
Due to this, the cursor size was interpreted as the default `24px`
instead of the actual size set via user.

---

### Tested

This fix has been tested with all possible combinations of the
following:

- [x] GNOME Normal Scale (100%, 200%, etc.)
- [x] GNOME Fractional Scaling (125%, 150%, etc.)
- [x] GNOME Cursor Sizes (**Settings > Accessibility > Seeing**, e.g.,
`24px`, `64px`, etc.)
- [x] GNOME Experimental Feature `scale-monitor-framebuffer` (both
enabled and disabled)
- [x] KDE (`cursor-shape-v1` protocol)

---

**Result:**

64px custom cursor size + 150% Fractional Scale:

We did not need to add the `*` as it was already matching one of them,
we actually need at least one of them, so making it optional was a
mistake.

Don't think we need to add release notes, as the change is only on main

Closes #20070

Release Notes:

- Fixed issue where files wouldn't open from the file explorer.
- Fixed "Open a new workspace" option on the desktop entry right-click
menu.

Context:

Zed consists of two binaries:

- `zed` (CLI component, located at `crates/cli/main.rs`)
- `zed-editor` (GUI component, located at `crates/zed/main.rs`)

When `zed` is used in the terminal, it checks if an existing instance is
running. If one is found, it sends data via a socket to open the
specified file. Otherwise, it launches a new instance of `zed-editor`.
For more details, see the `detect` and `boot_background` functions in
`crates/cli/main.rs`.

Root Cause:

Install process creates directories like `.local/zed.app` and
`.local/zed-preview.app`, which contain desktop entries for the
corresponding release. For example, `.local/zed.app/share/applications`
contains `zed.desktop`.

This desktop entry includes a generic `Exec` field, which is correct by
default:

```sh
Comment=A high-performance, multiplayer code editor.
TryExec=zed
StartupNotify=true
```

The issue is in the `install.sh` script. This script copies the above
desktop file to the common directory for desktop entries
(.local/share/applications). During this process, it replaces the
`TryExec` value from `zed` with the exact binary path to avoid relying
on the shell's PATH resolution and to make it explicit.

However, replacement incorrectly uses the path for `zed-editor` instead
of the `zed` CLI binary. This results in not opening a file as if you
use `zed-editor` directly to do this it will throw `zed is already
running` error on production and open new instance on dev.


Note: This PR solves it for new users. For existing users, they will
either have to update `.desktop` file manually, or use `install.sh`
script again. I'm not aware of zed auto-update method, if it runs
`install.sh` under the hood.

- Closes #19030

When `%U` is used in desktop entries, file managers pick this and use
it:

- When you right-click a file and choose "Open with..."
- When you drag and drop files onto an application icon

Adding it to CLI args, changes Flatpak desktop entry `Exec` from:

```diff
- Exec=/usr/bin/flatpak run --branch=master --arch=x86_64 --command=zed dev.zed.ZedDev --foreground
+ Exec=/usr/bin/flatpak run --branch=master --arch=x86_64 --command=zed --file-forwarding dev.zed.ZedDev --foreground @@u %U @@
```

This is Flatpak's way of doing `%U`, by adding `--file-forwarding` and
wrapping arg with `@@u` and `@@`.
Read more below
([source](https://docs.flatpak.org/en/latest/flatpak-command-reference.html)):

> --file-forwarding
>
> If this option is specified, the remaining arguments are scanned, and
all arguments that are enclosed between a pair of '@@' arguments are
interpreted as file paths, exported in the document store, and passed to
the command in the form of the resulting document path. Arguments
between "@@u" and "@@" are considered URIs, and any "file:" URIs are
exported. The exports are non-persistent and with read and write
permissions for the application.

Release Notes:

- Fixed Zed not visible in the "Open with" list in the file manager for
Flatpak.

Closes #20845

I'm uncertain about my placement for the logic to remove actions from

I think having this action exposed in the editor controls menu, close to
the inline Git Blame option, makes more sense than a more prominent item
somewhere else in the app. Maybe having it there will increase its
discoverability. I myself didn't know this until a few weeks ago! Next
steps would be ensuring the menu exposes its keybindings.

(Quick note about the menu item name: I think maybe "_Git Blame Column_"
would make more sense and feel grammatically more correct, but then we
would have two Git Blame-related options, one with "Git Blame" at the
start (Inline...) and another with "Git Blame" at the end (... Column).
I guess one had to be sacrificed for the sake of consistency 😅.)
