Lootable unit corpses (UNIT_DYNFLAG_LOOTABLE) now click-through over
blocking players, matching the existing behavior for interactable NPCs
and game objects. Adds isLootable() check to the interactable NPC test
and UNIT_DYNAMIC_FLAGS descriptor offset to shared offsets.
Also adds RELEASE_NOTES.md for tracking changes between releases, and
adds a checklist item in RELEASING.md to review it before publishing.
Extract duplicated WoW 1.12.1 addresses and game accessor functions
into shared modules (src/offsets.zig, src/wow.zig), replacing 5+
copies of getObjectByGUID, isInBattleground, isValidPtr, etc.
- src/offsets.zig: shared address constants (object manager, descriptor
fields, map/zone, core function addresses, D3D9/GX)
- src/wow.zig: shared accessor functions (pointer validation, object
manager traversal, field reads, unit helpers, battleground detection,
game function wrappers, raid target cache)
- Update 10 modules to import from shared instead of inline constants
- Remove outline/wow.zig (promoted to src/wow.zig)
- Trim outline/offsets.zig and markers/offsets.zig to module-specific only
