## Summary
Fixes https://github.com/astral-sh/ruff/issues/14807
I suspect that this broke when we updated notify, although I'm not quiet
sure how this *ever* worked...
The problem was that the file watcher didn't skip over `Access` events,
but Ruff itself accesses the `pyproject.toml` when checking the project.
That means, Ruff triggers `Access` events but it also schedules a
re-check on every `Access` event... and this goes one forever.
This PR skips over `Access` and `Other` event. `Access` events are
uninteresting because they're only reads, they don't change any file
metadata or content.
The `Other` events should be rare and are mainly to inform about file
watcher changes... we don't need those.
I also added an explicit handling for the `Rescan` event. File watchers
emit a `Rescan` event if they failed to capture some file watching
changes
and it signals that the program should assume that all files might have
changed (the program should do a rescan to *get up to date*).
## Test Plan
I tested that Ruff no longer loops when running `check --watch`. I
verified that Ruff rechecks file after making content changes.
