feat(v3.32.0): Plan-Validate-Execute Pipeline — 3-command AI-first workflow

New workflow for production teams: dynamic agent teams, ADR learning loop,
automated execution from PRD to merged PR.

Added:
- guide/workflows/plan-pipeline.md — complete workflow guide (philosophy,
  non-prescriptive AI-first, No Bandaids first principles, ADR learning loop,
  CLAUDE.md 120-line discipline, /clear context reset, cost profile)
- examples/commands/plan-start.md — 5-phase planning with 12-agent dynamic
  pool (trigger-based selection, Tier 0 Solo → Tier 4 Full Spectrum,
  planning-coordinator synthesis, auto-transition to validate)
- examples/commands/plan-validate.md — 2-layer validation (structural inline +
  8 specialist agents), ADR-aware auto-fix (Bucket A ~95% auto-resolve,
  Bucket B human input → new rule), issue persistence in metrics JSON
- examples/commands/plan-execute.md — worktree → TDD scaffold → level-based
  parallel agents → drift detection → quality gate → smoke test → PR squash
  merge → post-merge metrics → cleanup
- examples/agents/planning-coordinator.md — Opus synthesis agent: merges
  multi-agent reports into coherent task graph, resolves conflicts via ADR
  precedence, verifies plan completeness before output
- examples/agents/integration-reviewer.md — Opus runtime validator: connection
  params, async/sync consistency, env var completeness, library API
  correctness (WebFetch), OTEL pipeline validation

Updated:
- machine-readable/reference.yaml — 16 new indexed keys
- CHANGELOG.md — v3.32.0 entry with 6 detailed items
- VERSION, README.md, guide/cheatsheet.md, guide/ultimate-guide.md — bumped to 3.32.0
