feat(skills): implement Amazon Javelin and Spear skill tree with 1.13c parity (closes #461)

- Implement 10 Javelin & Spear skills: Jab (10), Power Strike (14), Poison Javelin (15), Impale (19), Lightning Bolt (20), Charged Strike (24), Plague Javelin (25), Fend (30), Lightning Strike (34), Lightning Fury (35)
- Wire 1.13c 5-band scaling, synergy matrices, mana curves, casting delays (Poison Javelin 12f, Plague Javelin 100f)
- Add comprehensive adversarial stress test suite adv-ama-javelin-spear-stress.test.ts (13/13 passing)
- Maintain BATCH1_SKILLS length = 38 invariant and zero runtime MPQ reads
- 100% typecheck clean and 0 regressions against existing test suite
