Thomas Güttler 656d4b46d7 Optimize deployment, fix E2E flakiness, and implement database-backed threading

- Optimize task deploy-android with marker files and source/generate tracking.
- Fix flaky Android E2E test with pumpAndSettle and safety delays.
- Implement global CrashScreen and error handlers in main.dart.
- Refactor threading to use a persistent Threads table for performance.
- Add database indexes and migration for schema v18.
- Enhance coverage gate with ghost path checks and increased coverage (82%).

Introduction

Continue the momentum from the safety hardening and infrastructure work. The focus is on making the app ready for real-world use with robust error handling and performance optimizations.

Create several small commits. Every commit should be self contained.

while working create/append to plan.log, so that the user sees what you are working on.

Tasks

0. deploy-android

Make task deploy-android work.

0.5 Debug duration of deploy-android

Is there a way to make deploy-android faster?

Use task --verbose to see what gets done.

Maybe avoid doing things again, when nothing changed. Taskfile has features to avoid calling things again, when the input has not changed.

1. Fix Android E2E Race Condition (aliceTile)

The Android E2E test integration_test/app_e2e_test.dart is flaky. It fails at tap(aliceTile) with "0 widgets" even though pumpUntil found it. The current "double pumpUntil" fix isn't reliable enough. Investigate if the animation state or the Drift stream propagation is the culprit.

2. Implement Global Crash Screen

Wrap main() in runZonedGuarded to catch unhandled async errors. Implement a CrashScreen widget that shows the stack trace and a "Copy to Clipboard" button for user reporting.

3. Database-Backed Threading

Currently, emails are grouped into threads in-memory in the repository. Refactor to store thread relationships in the local SQLite database. This is necessary for performance on mailboxes with thousands of messages.

4. Implement Undo for Bulk Actions

Add a global "Undo" snackbar after deleting or moving emails. The system needs to handle the three sync states:

Queued (easy to undo)
In-progress (cancel network call)
Finished (requires a reverse move/un-delete)

5. Transition to Real Account Testing

Prepare the integration tests to run against a real test account (si3e2e@thomas-guettler.de) instead of the local Stalwart server. This verifies the app against real-world network latency and RFC edge cases.

6. Coverage Gate Maintenance

Reduce the _excluded list in scripts/check_coverage.dart. Add a test to ensure the exclusion list doesn't contain files that no longer exist ("ghost paths").
