codex: mark cf2 source stamps historical
Add 17 source-verified reference pages (content catalogs, module/SQF references, tooling, commander handbook)
Fill documentation coverage gaps found by a source-vs-wiki gap analysis: the wiki
documented how systems work but never cataloged what content actually exists.
New pages:
- Content catalog: faction unit/vehicle roster, cross-faction upgrade costs,
defense structures, per-faction artillery, AI squad team templates
- Map content: Chernarus, Takistan
- Module reference: IRS IR-smoke countermeasure, Arty special munitions (SADARM/ILLUM)
- Core SQF API: spawn primitives, kill/score pipeline, waypoint helpers, player-AI watchdog
- Tooling/operator: LoadoutManager data model, Discord status bot, GLOBALGAMESTATS extension
- Player: Commander's Handbook (surfaces in-repo commanderGuide.md, costs verified vs config)
All claims source-cited against master cf2a6d6a4 (Arma 2 OA 1.64) and adversarially
verified citation-by-citation. Wired into _Sidebar, Home routes and agent-context.json.
