feat(tracker): add sample offset and humanization
Implements two tracker realism features:
1. Sample Offset (compile-time):
- Add offset_sec field to NoteParams and Sample structs
- Parse OFFSET parameter in SAMPLE directive
- Apply timing shift during compilation (zero runtime cost)
- Use for attack-heavy samples to align perceived beat
2. Humanization (runtime, deterministic):
- Add humanize_seed, timing_variation_pct, volume_variation_pct to TrackerScore
- Parse HUMANIZE directive with SEED/TIMING/VOLUME params
- Apply per-event RNG jitter using std::minstd_rand
- Deterministic: same seed produces identical output
Both features work in real-time playback and WAV export.
