docs: update STATE.scm with Task #2 and #3 completion

- Completion percentage: 70% → 85%
- Phase: migration → implementation
- Current focus: Tauri backend FFI implementation

Work completed:
- Task #2: UI components wired up (already fully implemented)
- Task #3: npm→Deno migration complete (33 tests, Vitest removed)

Next up:
- Task #4: Implement Tauri backend commands with rescript-tauri + rescript-zig-ffi
