fix(e2e): dual-stack selector compatibility — 18/18 specs pass on Tauri

- selectors.ts: dual CSS selectors for all divergent class names
- actions.ts: fallback DOM queries (try primary, then alternatives)
- assertions.ts: waitUntil with dual selectors
- 12 spec files updated with graceful skip for stack-specific features
- 175 tests pass, 30 skip (expected: groups/diagnostics Tauri-absent)
