Skip .git/lfs FS events (#25927)

Closes https://github.com/zed-industries/zed/issues/25865
Closes https://github.com/zed-industries/zed/pull/25915

In the issue, Zed had caused `.git/lfs/tmp/466102258`-like files to
appear in the directory, which lead to background FS event listener to
handle this as an update, incrementing snapshot's `scan_id`, which lead
to git status rescan, which caused another increment to `status_scan_id`
— incrementing either of the IDs causes the related repo data to be
considered "changed:


https://github.com/zed-industries/zed/blob/41b45eaba798a56e596857fa497c862050788bc7/crates/worktree/src/worktree.rs#L1590-L1605

hence propagating events to the other parts of the system (e.g. git
blame, which was also active in the issue's case)

```
[2025-03-01T20:01:08+01:00 DEBUG worktree] ignoring event ".git/lfs/tmp/466102258" within unloaded directory

```

Due to repo update events sent, another `.git/lfs/tmp/` entry is
created, things start over...

The PR fixes this by ignoring any `.git/lfs/` directory-related FS
events, as needed for the current git status update heuristics.

https://github.com/zed-industries/zed/pull/25915 tried to follow further
and `scan_id` and `status_scan_id` but we do not store all git state in
memory, e.g. head

as
[tests](https://github.com/zed-industries/zed/actions/runs/13631960559/job/38101504549?pr=25915)
show.

Release Notes:

- Improved `.git` scan heuristics
