Exclude platform dirs from analysis; refresh the lockfile

analysis_options.yaml: keep the analyzer out of android/ios/web/windows/
macos/linux. A no-op today — those directories hold no Dart (checked: 0
files each, and `flutter analyze` reports the same two pre-existing infos
either way) — but it stops generated platform Dart from ever entering the
lint surface.

pubspec.lock: transitive bumps (matcher 0.12.19->0.12.20, test_api,
leak_tracker and friends) picked up by the `flutter pub get` runs during
the file-cap refactor. No direct dependency changed.

Both had sat uncommitted through that refactor because I misattributed
them to kuhy and deliberately left them unstaged; they are this machine's
work, so they belong in the history.

Verified: flutter analyze clean (same 2 pre-existing infos), 313 tests
pass, file-length gate exits 0.
