Krzysztof kuhy Rudnicki 9d2aa1c178 Enforce the 250-line file cap, and split the first four files
Wires the shared gate (~/utils/scripts/check_file_length.sh) into a new
.pre-commit-config.yaml as a local hook, checking only the files in the
commit and failing rather than warning. No baseline, no allowlist.

The repo had a hand-written .git/hooks/pre-commit running two checks;
both are ported verbatim into the config rather than dropped, with the
version bump ordered last so it cannot rewrite pubspec.yaml for a commit
a gate is still about to reject. scripts/install_hooks.sh now installs
pre-commit (and removes the legacy hook) instead of writing its own.

.github/workflows/file-length.yml runs the same check on push, kept
separate from release-apk.yml so an over-long file fails lint rather than
blocking an APK release.

Splits the four cleanest violations, all behaviour-preserving:

  note_template.dart      370 -> 203 + parser (186)
  firebase_backend.dart   308 -> barrel (24) + project/store/client
  port_guard.dart         315 -> 232 + linux_system_probe (100)
  notes_list_screen.dart  698 -> 225 + 5 widget/nav files

Where a file had external callers, the original path stays as a barrel
that re-exports the split parts, so no call site changed.

Verified: 313 tests pass, coverage identical at 99.9% / 1922 lines
(per-file too -- notes_list's 281 covered lines are now 81+75+51+41+22+11),
flutter analyze clean, and a staged 260-line file makes git commit fail.

# three checks in one hand-written hook is the point where "just a plain
