docs(02-03): complete MP3 encoder and output flag plan

- Create 02-03-SUMMARY.md with TDD flow documentation
- Update STATE.md: advance to last plan, 100% progress, add decisions
- Update ROADMAP.md: phase 02 complete (3/3 plans)
- Mark requirements OUT-01, OUT-02, OUT-03 complete

3. Drone layer amplitude rises and falls with traffic volume over time — sustained traffic sounds louder, quiet periods fade
4. User can specify output path via `-o` flag; it defaults to `netsynth-<timestamp>.mp3` when omitted
5. An empty (zero-packet) input produces a clear error message instead of a corrupt or zero-byte MP3
**Plans:** 2/3 plans executed
**Plans:** 3/3 plans complete
Plans:
- [x] 02-01-PLAN.md — Environment setup (gcc, ffprobe, go-lame), synth config table, oscillator, EMA layer with tests
- [x] 02-02-PLAN.md — Stereo mixer (constant-power panning), OscillatorBank multi-layer rendering with tests
- [ ] 02-03-PLAN.md — MP3 encoder package, zero-packet guard, -o CLI flag, ffprobe integration test
- [x] 02-03-PLAN.md — MP3 encoder package, zero-packet guard, -o CLI flag, ffprobe integration test
### Phase 3: Pipeline Integration and MVP
**Goal**: Live capture flows end-to-end into audio synthesis — the complete v1 MVP: run, capture, Ctrl+C, get an MP3
