milestone(editor): v1.0.0 — complete world editor with full open format pipeline

191 commits, 11.5k lines, 55 files. Both targets clean, zero warnings.

World Editor v1.0.0 feature-complete:
- 6 modes: Sculpt, Paint, Objects, Water, NPCs, Quests
- 30+ terrain generators and tools
- Full painting, object placement, NPC, and quest pipelines
- Project management with git collaboration
- Content pack import/export with validation

All 6 Blizzard formats replaced with novel open alternatives:
- ADT → WOT/WHM (WHM1 magic)
- WDT → zone.json
- BLP → PNG (auto-converted)
- DBC → JSON (auto-converted)
- M2 → WOM (WOM1 magic, auto-converted)
- WMO → WOB (WOB1 magic)

Client integration: auto-loads WOT/WHM terrain + WOM models
Content pipeline: Editor → Export → WCP Pack → Share → Client loads
