test: add comprehensive sessions store coverage (escapeHtml, generateHtmlExport, all exports)

Adds 55 tests for clipboard store pure functions (detectLanguage for 12
languages + formatTimestamp with fake timers) and 13 tests for the
notification rules state machine (reconnect transition logic and no-op
handlers). Total test count now 698 across 30 files.

 ## Testing Requirements
 
-**All changes MUST include tests.** This is non-negotiable — no feature, bug fix, or refactor should be committed without corresponding test coverage. If a change cannot be tested (e.g. pure UI layout, Tauri IPC calls that are impossible to mock), document why in a comment.
+All new features, fixes, and significant changes should include tests whenever possible:
 
 - **Frontend tests**: Use Vitest with `@testing-library/svelte` for component tests
 - **Test files**: Place test files next to the code they test with `.test.ts` or `.spec.ts` extension

-### Adding Tests for All Changes
+### Adding Tests for New Features
 
-Every change — features, bug fixes, refactors — must include tests:
+When developing new features, always add corresponding tests:
 
 1. **Before implementing**: Consider what needs testing (happy path, edge cases, errors)
 2. **During implementation**: Write tests alongside the code
 3. **After implementation**: Run `pnpm test:coverage` to verify coverage remains high
 4. **Before committing**: Ensure `check-all.sh` passes (includes all tests)
 
-**Do not commit changes without tests.** The goal is to maintain near-100% coverage as the codebase grows, so future refactoring can be done with confidence!
