Add Phase 0 test harness (vitest + ESLint) and fix build config

- Add vitest unit tests for Zustand app store state transitions (6 tests)
- Add mock speech-engine WebSocket protocol integration test (spawns server.py --mock on a free port)
- Add ESLint 10 flat config with typescript-eslint; add typecheck/lint/test scripts to package.json
- Fix pre-existing tsc -b breakage via noEmit in tsconfig.node.json; add dedicated tsconfig.tests.json project for Node-side tests
- Track src-tauri/Cargo.lock for reproducible Rust builds; enable protocol-asset Tauri feature
- Ignore generated artifacts (*.tsbuildinfo, src-tauri/gen/, emitted vite.config.js/.d.ts); remove stale emitted vite config copies
- Update AGENTS.md agent guide (demo scope lock, roadmap, verification commands)
- Add HANDOFF.md documenting Phase 0 state and remaining steps for the next agent
