b3nw 9bb1dc8573 fix(#4085): surface dirty install state in update-check payload
The update-check payload now carries a `dirty: bool` reflecting the
working-tree state vs HEAD, computed via the same `git diff-index
--quiet HEAD --` primitive already used by `_dirty_suffix()`. A dirty
install at-or-past the latest release tag used to silently report
"Up to date" with no remediation affordance; the Settings panel
can now read this flag to offer `apply_force_update` (which already
does `git checkout .` + `git reset --hard` to reset to a clean
latest).

The probe is conservatively clean on real errors (timeout, missing
git, fatal) so a transient probe failure never produces a false-
positive "local changes" alert.

Closes #4085

"""
Tests for api/updates.py -- specifically the diagnostic code paths added
in fix/223-update-pull-failed-diagnostics (PR #227).
Tests cover the four new branches in _apply_update_inner():
1. fetch fails → network error message
2. pull fails + diverged history → recovery command with git reset --hard
3. pull fails + no upstream tracking → recovery command with set-upstream-to
4. pull fails + generic fallback → raw git output truncated at 300 chars
