Closing a presentation only offered Cancel or "Save and close", so
unsaved edits could only be dropped by force-quitting. That left an
autosave recovery snapshot behind, creating version ambiguity between
the saved file on disk and the restored unsaved copy on next launch.
Add a third "Niet opslaan" (discard) choice to the close/quit dialog.
Discarding closes without saving; closeTab() and _destroy() already
clear the recovery files, so no shadow version remains and there is a
single unambiguous version afterwards.
Register the "Niet opslaan" string for all 8 supported languages.

The presenter view now doubles as a rehearsal clock that measures without
coaching: a countdown against a target time, the time spent on the current
slide, and an end-of-run summary (total vs. target and per-slide times, with
copy-to-clipboard). Timing lives in a plain, unit-tested RehearsalController fed
via an idempotent observe() on every build, so it captures every navigation
path. The default target is stored in AppSettings; live adjustment is the K key
(typed as MMSS). All rehearsal state is session-only -- nothing is written to
disk or into the .md file.
- New: models/rehearsal.dart, services/rehearsal_controller.dart,
widgets/presentation/rehearsal_summary.dart, plus a controller unit test.
- Presenter: countdown + per-slide timer in the clock bar, K to set the target,
R resets the run, end-of-run summary dialog, and help/cheatsheet entries.
- Settings: presentationTargetSeconds (default target) with a dropdown in the
General tab, threaded into FullscreenPresenter.present().
- l10n: new Dutch source strings translated in all seven languages.
- Docs: README, CHANGELOG, USER_GUIDE, SHORTCUTS, ARCHITECTURE.
Also bundles a pre-existing in-progress change already in the working tree: wire
the existing ThemeProfile.tableHeaderBackgroundColor into table rendering
(preview, HTML export, file_service) and the settings dialog, plus its
translations.

Enforce an optional TLP release ceiling at the single export chokepoint
so no format (PDF/PPTX/HTML) can bypass it. Classifying a deck stays
optional; the gate only blocks decks classified above the configured
ceiling, and is off by default.
- ClassificationPolicy + ExportDecision: pure, tested decision logic
(release ceiling, fail-closed; null = no gate).
- ExportService.export() evaluates the policy first and refuses without
building or writing anything when blocked.
- Persist the ceiling as maxReleaseExportTlpKey in app settings/prefs
(default off) with a setter on SettingsNotifier.
- Export dialog runs the same check up front and explains a blocked
export before any work starts; app shell builds the policy from
settings.
- Tests: classification_policy_test plus export_service chokepoint tests
asserting a blocked export fails and writes no file.
- Docs: CHANGELOG, README, USER_GUIDE, ARCHITECTURE, SECURITY.
