Upstream Mapster relies on the CurseForge packager to fetch its libs
at release time; the raw repo has no Libs/ folder, so the freshly-
imported addon failed to load (LibStub missing).
- Vendored canonical Ace3 from coa-ace3 (11 libs Mapster's TOC loads:
LibStub, CallbackHandler-1.0, AceAddon-3.0, AceEvent-3.0, AceHook-3.0,
AceDB-3.0, AceDBOptions-3.0, AceLocale-3.0, AceGUI-3.0, AceConsole-3.0,
AceConfig-3.0). This brings the CoA-compat FileDataID / BlizOptionsGroup
parent-guard / Settings.* fallback / AceDB falsy-defaults patches.
- LibBabble-Zone-3.0 and LibWindow-1.1 vendored from the working PTR
install (not part of Ace3).
- TOC: replaced @project-version@ CurseForge placeholder with the real
release string 1.3.9-coa.2 so the in-game About panel reads correctly.
Mapster source itself was clean against the PORTING.md checklist
(no FDID calls, no retail-only globals, no Minimap mask trap, no CLEU
arg mismatch) — expected, since 1.3.9 was the WotLK-era release.
