Plan 2: Curated Content, Abilities, Objectives, and Scenario Validation.
Adds the curated content library (archetypes, abilities, terrain behaviors),
per-round objective control, both victory conditions, and full scenario
validation. 9 production files, 7 test files, 130/130 tests, PHPStan level 6
clean, PHPCS clean. See docs/superpowers/plans/2026-07-05-curated-content-
abilities-and-objectives.md for the implementation plan.
Final-review-driven changes (Tasks 6/M1, I1 from the ledger):
- Drop the redundant abilities-list check in CombatEngine::useAbility.
By construction (Scenario::__construct enforces the allowlist), any
ability the unit 'knows' is also archetype-allowed; the second check
alone is sufficient and removes a dead code path.
- Update testUseAbilityRejectsAnAbilityTheArchetypeForbids to assert the
'Unit archetype forbids that ability.' message it actually exercises.
- Compute $template once in Scenario::__construct's per-unit loop and
drop the redundant catalog lookup on the next line.
