This commit removes the CI step that installs LLVM on Windows because:
1. It was constantly failing when I worked on [1]
```text
Failed in attempting to update the source: winget
The `msstore` source requires that you view the following agreements before using.
Terms of Transaction: https://aka.ms/microsoft-store-terms-of-transaction
The source requires the current machine's 2-letter geographic region to be sent to
the backend service to function properly (ex. "US").
Failed when searching source: winget
An unexpected error occurred while executing the command:
0x8a15000f : Data required by the source is missing
No packages were found among the working sources.
```
2. Actually, we don't need to install it since the Windows Github
action image already includes it. See [2]

The file search extension relies on the OS's desktop search to work, and it
is possible that the desktop search indexer may not index the search paths
we specify.
This commit adds a hook that signals to the indexer and lets it index
the paths we need. This hook will be invoked when:
* initialing the extension
* enabling the extension
* upon every configuration change
to make our best effort to fix the issue.
This commit implements the file search extension for Linux with the
GNOME desktop environment by employing the engine that powers GNOME's
desktop search - Tracker.
It also fixes an edge case bug that the search and exclude path
configuration entries will not work. For example, say I set the search path
to ["~/Dcouments"], and I have a file named "Documents_foobarbuzz" under
my home directory, this file is not in the specified search path but
Coco would return it because we verified this by checking string prefix.
Claude Code found this when I asked it to write unit tests. Thank both
tests and Claude Code.
