chore(openspec): cleanup p2-mad-core-t1 + add legacy-quality design.md

[rubenvdlinde]

Summary

Completes the last 2 OpenSpec changes still in the BLOCKED bucket for decidesk. Spec-only — no code changes.

p2-minutes-and-decisions-core-t1

• Moved specs.md to the canonical OpenSpec path specs/p2-minutes-and-decisions-core-t1/spec.md, matching the directory convention used by sibling p2-* changes (motion-and-voting, agenda-management, meeting-management-*, minutes-and-decisions-other-t2).
• Pure relocation via git mv — spec content unchanged (all 7 REQ groups: REQ-CDM, REQ-PPD, REQ-SDL, REQ-URG, REQ-ADL, REQ-ATR, REQ-ARC, plus REQ-NFR non-functional requirements).
• Note: actual repo state had only specs.md (not both files as described in the brief). Moving to the canonical location is the equivalent cleanup — the canonical path now exists and the wrong-location file is gone.

decidesk-legacy-quality-cleanup

• Added design.md (~560 words) covering:
  • Scope: PHPCS exclude-pattern burn-down (3 files), PHPMD baseline burn-down (51 lines), PHPStan first-run, CI wiring, documentation.
  • Execution order: 6 sequential phases so each PR re-baselines cleanly.
  • Relationship to quorum- migrations:* inverse scope — quality config vs. domain logic; non-overlapping file sets; safe to run in parallel; unified gate (Phase 5) catches any new sniff violations from quorum-* refactors.
  • Risk assessment: burn-down cascades, PHPStan first-run volume, unified-gate red flips, parallel quorum-* work.
  • Success criteria: zero phpcs excludes, deleted phpmd baseline, phpstan in check:strict, CI wiring, weekly cron, README + app-config.json updated.

Test plan

• Confirm openspec/changes/p2-minutes-and-decisions-core-t1/specs/p2-minutes-and-decisions-core-t1/spec.md exists and matches the sibling p2-* directory layout.
• Confirm openspec/changes/p2-minutes-and-decisions-core-t1/specs.md no longer exists.
• Confirm openspec/changes/decidesk-legacy-quality-cleanup/design.md is present alongside proposal.md and tasks.md.
• (Optional) Diff design.md against quorum-declarative-migration/design.md for stylistic consistency.

Notes

• composer check:strict was skipped per the watchdog rules (spec-only change, no PHP touched).
• Sibling p2-* changes also do not pass openspec validate (they use REQ-XXX-NNN headings instead of ## ADDED Requirements / #### Scenario: delta headers); this is a project-wide convention deviation, not introduced or aggravated by this PR.
