v2.7.0 - Combat Modernization

This release ships the combat modernization compatibility release. It moves live combat, equipment, NPC, OLC, protocol, save/load, simulator, and diagnostic surfaces to modern combat fields and vocabulary while retaining legacy readers and compatibility mirrors for the follow-up 8E removal branch.

Highlights

• Reworked combat around modern Accuracy, Expertise, Attack Power, and Armor Rating fields.
• Added normalized combat table handling for miss/evasion and Armor Rating mitigation telemetry.
• Migrated object equipment applies, Mobile OLC, area save output, NPC construction, summons, clones, quest mobs, and diagnostics to modern combat stat naming/conversion paths.
• Updated player, pet, and mount saves to write modern combat fields and rebuild derived Armor Rating from equipment and affects after load.
• Refreshed score, attribute, identify, compare, loot, crafting, GMCP/MSDP, and combat simulator output with modern stat names.
• Retained reusable audit scripts with ignored outputs under reports/.
• Consolidated feature docs into docs/changes/v2.7.0-TODO.md.
