**Files Deleted:** None

**Quality Gate Results:**
- `npm run typecheck` (frontend): **PASS** — zero errors
- `npm run lint` (frontend): **PASS** — zero warnings
- Python syntax check (backend main.py + seeds): **PASS** — exit code 0
- Type uniqueness verification:
  - `interface Session` appears exactly once (in types/session.ts)
  - `interface ToolInstance` appears exactly once (in types/tool-instance.ts)
  - `interface ToolType` appears exactly once (in types/tool-type.ts)
  - `interface GitRepository` appears exactly once (in types/git-repository.ts)

**Blockers/Deviations:**
- None. All types successfully centralized with backward-compatible re-exports from API modules.
- The `types.ts` file at `apps/web/src/types.ts` still exists as a legacy re-export file to avoid breaking any remaining consumers. It will be removed in a later phase once all imports are confirmed migrated.
