docs(03): complete Phase 3 via parallel execution

Phase 3 (Job Management Core) executed with 4 parallel agents:
- 03-01: Job submission form (15 min)
- 03-02: Job edit form (12 min)
- 03-03: Admin notification (8 min)
- 03-04: Admin UI enhancements (15 min)

Execution waves:
- Wave 1: 03-01 (independent)
- Wave 2: 03-02, 03-03 (both depend on 03-01, no file conflicts)
- Wave 3: 03-04 (depends on 03-03 via shared files)

All 4 plans completed successfully with 0 failures.
Wall clock time: ~50 min (parallelized from ~60 min sequential estimate)

Updated:
- ROADMAP.md: Phase 3 marked complete
- STATE.md: Progress 44%, velocity metrics updated, decisions recorded
