test(compat): mod compatibility matrix against the 25-mod reference profile

[aram-devdocs]

Boot the game clean with the 25-mod reference profile (docs/04-reference/prior-art.md) plus both our plugins; audit Harmony patch collisions; state SailwindModdingHelper coexistence; publish the compat matrix.

Blocked by #15. Seed list recorded; each row gets a checked result as tested.

Handoff: The 25-mod reference seed list is recorded (docs/04-reference/prior-art.md). Remaining (live, blocked on #15's in-game handshake): boot modded Sailwind with the 25-mod reference profile + both our plugins, audit Harmony patch collisions, verify SailwindModdingHelper coexistence, and fill each matrix row with a checked result. This is inherently a manual Phase-F boot.
