feat: add LexAI status bar and suggestion panel

- Implemented a status bar item for LexAI with dynamic status updates (ready, processing, notReady).
- Created a suggestion panel for displaying and interacting with AI-generated suggestions.
- Added functionality for accepting, regenerating, and discarding suggestions within the suggestion zone.
- Introduced configuration options for writing style, prompt patterns, personas, and formats.
- Integrated progress indicators for long-running tasks and improved user feedback.
- Established TypeScript configuration for the vscode package.

+name: design-review
+description: Heuristic + accessibility review of implemented user-facing UI against its design spec and the design system, AFTER the build. Returns P0–P3 findings with file/line evidence; read-only. Owner — ux-ui-designer; runs concurrently with the verifier. Required at medium+ risk for any user-facing change.
+---
+
+Review what was actually built — templates, widgets, copy, states — against the spec (`docs/design/<feature>.md` if present), `docs/DESIGN_SYSTEM.md`, and these lenses. Read-only: findings and smallest fixes, never patches.
+
+1. **Task efficiency.** Steps/taps to complete the user's job vs the spec's target; unnecessary inputs where a preset, dropdown, or default would do; the primary action visually primary on every screen.
+2. **State completeness.** Every state the spec names exists in code: empty, loading, error, success, and — for offline-capable surfaces — offline, queued, sync-pending, sync-rejected. Grep for the state handling, don't assume; an unhandled state is at least P1.
+3. **Consistency.** Components, spacing, and naming match `DESIGN_SYSTEM.md` and neighboring screens; new one-off patterns without a design-system entry are findings.
+4. **Copy + i18n.** Every user-visible string localized in all supported locales (grep for hardcoded literals in templates/widgets); tone and terminology match the copy rules; errors say what to DO, not just what failed.
+5. **Accessibility.** Tap targets ≥ 48dp, WCAG AA contrast, focus order, labels on icon-only controls, form errors announced next to their fields.
+6. **Platform ergonomics.** Mobile: reachability, keyboard types, sunlight-legible contrast, battery-conscious patterns. Web: keyboard navigation, dense-screen scanability, bulk-action affordances.
+
+Rank findings **P0** (blocks the user's job or data comprehension — e.g. money state invisible), **P1** (missing state, broken i18n/a11y on a core path), **P2** (inconsistency, inefficiency), **P3** (polish). Each finding: evidence (file/line or reproduction), impact, smallest fix. Do not restate the spec, praise the work, or invent P3s to seem thorough — state `none` after meaningful checks if the build holds.
+
+Return exactly: **Verdict** (accept / accept with follow-ups / return to builder) · **Findings** (P0–P3 or `none`) · **Checks performed** (lenses run, files inspected) · **Design-system delta** (or `none`).
