v2.5.0

Adds the red-team adversarial diff reviewer and rewires the implement skill around it, closes agnosticism gaps so the loop works across projects, fixes cross-file inconsistencies found in review, and removes every em dash from the repo.

Added

• red-team agent: adversarial diff reviewer porting the code-review + simplify engine (5 correctness angles, 4 cleanup angles, a runtime conventions angle, recall-biased 3-state verify, gap sweep). Modes: bugs, cleanup, both. Cleanup mode is a standalone tidy pass that can apply fixes.

Changed

• Phase 6 quality gate spawns review-impl + red-team in parallel via the Agent tool instead of invoking /code-review, which a skill cannot trigger from the main loop.
• red-team is no longer git-only: shows git as the common case but instructs substituting another VCS or asking for the changed set, and treats a tracker/plan path as context, not the review target.
• /implement degrades gracefully with no PROJECT.md: infers and confirms build/test commands, notes the miss, suggests creating one.
• Conditional post-implementation docs; calibration guidance for strong-instruction-following models.

Fixed

• review-impl no longer flags a missing post-impl doc as a false finding on small changes.
• Plan-review gate branches on PASS-WITH-WARNINGS (the real verdict), not WARN.
• /implement reads the spec directory from PROJECT.md, matching /spec.
• README documents both PROJECT.md templates and the project-configs examples.

Removed

• The extension.yml spec-kit manifest; plugin.json is the single source of truth.
• Dependency on /code-review from within the implement skill.
• Every em dash, replaced with standard punctuation.
