v6.1.3: D9/D60 engine upgrade + 5 bottleneck rules tuned

Engine (yoga_engine.py):
- Added D60/Shashtiamsa context injection (d60_house_of, d60_sign_of, etc.)
- Added D9 dignity queries (is_exalted_in_d9, is_own_sign_in_d9, etc.)
- Added functional_malefics() / functional_benefics()
- Added is_shashtiamsa_evil/good() and vaiseshikamsa_score()
- Exposed all new methods to rule expression sandbox

Data (_compute_one_chart.py):
- Generate D60 positions alongside D1/D9
- Inject D60 into context for all computed charts

Rules (yoga_rules.json):
- thrikaala_gnana: D1 strong = exalted/own/moola only (kendra/trikona removed)
  + D9 strong check (at least 1 of 3 in D9 exalted/own/moola)
  FP: 12→0, FN: stable
- dharidhra: restored method1 (L2/L11 in dusthana + unfriendly navamsa + malefic aspect)
  FN reduced
- bandhubhisthyaktha: added is_shashtiamsa_evil(lord_4)
- nishkapata: added vaiseshikamsa_score(lord(1)) >= 15
- kapata: reverted functional_malefics (caused 22 FN), back to MALEFICS

Validation:
- FP: 45→39 (-6)
- FN: 72→67 (-5)
- F1: 94.35%→94.88% (+0.53%)
- Precision: 95.60%→96.18% (+0.58%)

New scripts:
- scripts/add_d60_to_test_charts.py: batch D60 augmentation
- scripts/ashtottari_dasha.py, yogini_dasha.py, kalachakra_dasha.py
- scripts/report_orchestrator.py

D60 data added to all 60 standard test charts.
