test: add e2e tests for upgrade indicator lifecycle

Add 21 end-to-end tests covering the full upgrade indicator flow:
- Full lifecycle: fresh install → UpdateAvailable → indicator shown →
  Updated → indicator hidden
- F1 regression: stale indicator after autoupgrade is cleared
- F2 regression: downgrade arrow prevention with `semver.gt()`
- F3 regression: empty/corrupted/non-string KV values rejected
- Semver integration: prerelease, build metadata, v-prefix handling
- Edge cases: rapid events, Updated without UpdateAvailable, same
  version available as current

Uses mock KV store pattern consistent with codebase test conventions
(algorithm extraction, no Solid.js context required).
