fix(ui): remove read-only contract violations and stale build artifacts

- Remove analyze_codebase tool from mcp-tools.ts (violated read-only contract)
- Remove AnalyzeResponse interface from types/api.ts (unused after above)
- Remove vendor-d3 manual chunk from vite.config.ts (d3 not imported)
- Clean stale build artifacts (39 files from prior builds)
- Rebuild frontend with clean output (5 chunks, no d3 dead weight)
