feat(ultraplan-local): v2.2.0 — /ultra-cc-architect-local

New optional command between /ultraresearch-local and /ultraplan-local that
matches brief+research against Claude Code features (hooks, subagents, skills,
output-styles, MCP, plan-mode, worktrees, background-agents) and produces an
architecture note with brief-anchored rationale plus explicit gaps.

Added:
- commands/ultra-cc-architect-local.md (--project, --fg, --quick, --no-gaps)
- agents/architect-orchestrator.md (opus) — 6-phase background orchestrator
- agents/feature-matcher.md (sonnet) — fallback-ranked feature proposals
- agents/gap-identifier.md (sonnet) — 4 gap classes with issue-ready drafts
- agents/architecture-critic.md (sonnet) — hallucination gate as BLOCKER
- skills/cc-architect-catalog/ — SKILL.md + 10 seed entries (reference/pattern)

Changed (non-breaking):
- commands/ultraplan-local.md — auto-discovers architecture/overview.md
- agents/planning-orchestrator.md — cross-references cc_features_proposed
- plugin.json — 2.1.0 → 2.2.0, description, cc-architecture keyword
- CHANGELOG, README, CLAUDE.md (plugin + marketplace root)

Pipeline becomes brief → research → architect → plan → execute. Architect is
optional; existing project dirs keep working unchanged.

+Five commands, one pipeline with clear division of labor:
 
 - **`/ultrabrief-local`** — Capture intent. Dynamic, quality-gated interview: a section-driven completeness loop (Phase 3) followed by a `brief-reviewer` stop-gate (Phase 4, max 3 review iterations). Required sections must reach an initial-signal gate AND pass review across completeness, consistency, testability, scope clarity, and research-plan validity before `brief.md` is written. Identifies research topics with copy-paste-ready `/ultraresearch-local` commands. Optional auto-orchestration runs research + planning in foreground. Always interactive.
 - **`/ultraresearch-local`** — Gather context. Deep multi-source research with triangulation: 5 local agents + 4 external agents + Gemini bridge, producing structured briefs with confidence ratings. Makes no build decisions.
-- **`/ultraplan-local`** — Transform intent into an executable contract. Per-step YAML manifests (`expected_paths`, `commit_message_pattern`, `bash_syntax_check`). Plan-critic is a hard gate on manifest quality. Requires a task brief as input (`--brief` or `--project`).
+- **`/ultra-cc-architect-local`** *(optional, v2.2)* — Match Claude Code features to the task. Reads `brief.md` + `research/*.md`, consults a seeded CC-feature catalog skill (hooks, subagents, skills, output styles, MCP, plan mode, worktrees, background agents), and produces `architecture/overview.md` with brief-anchored rationale plus `architecture/gaps.md` with issue-ready drafts for missing catalog entries. Hallucination gate (enforced by `architecture-critic`) blocks proposals for features not covered by the catalog.
+- **`/ultraplan-local`** — Transform intent into an executable contract. Per-step YAML manifests (`expected_paths`, `commit_message_pattern`, `bash_syntax_check`). Plan-critic is a hard gate on manifest quality. Requires a task brief as input (`--brief` or `--project`). Auto-discovers the architecture note when present and cross-references its `cc_features_proposed` against exploration findings.
 - **`/ultraexecute-local`** — Execute the contract disciplined. Manifest-based verification, independent Phase 7.5 audit from git log + filesystem (ignores agent bookkeeping), Phase 7.6 bounded recovery dispatch for missing steps. Step 0 pre-flight catches sandbox push-denial before any work. `--validate` mode offers a fast schema-only sanity-check between planning and execution.
 
-All artifacts land in one project directory: `.claude/projects/{YYYY-MM-DD}-{slug}/` contains `brief.md`, `research/NN-*.md`, `plan.md`, `sessions/`, and `progress.json`. `--project <dir>` works across `/ultraresearch-local`, `/ultraplan-local`, and `/ultraexecute-local`.

-v2.1 (non-breaking) replaces the hardcoded Q1–Q8 interview with a dynamic, quality-gated loop; `brief-reviewer` now emits machine-readable per-dimension JSON scores so `/ultrabrief-local` can use it as an internal stop-gate. v2.0 extracts the interview from planning: briefs are reviewable artifacts with explicit intent, research plan, and falsifiable success criteria — each a contract that downstream agents (`brief-reviewer`, `plan-critic`, `scope-guardian`) can validate independently. v2.0 is breaking: `/ultraplan-local` no longer runs an interview and requires `--brief` or `--project`. See `plugins/ultraplan-local/MIGRATION.md`.
+v2.2 (non-breaking) adds the optional `/ultra-cc-architect-local` step between research and planning. The architect phase is backed by a versioned catalog skill (`cc-architect-catalog`) with 10 seed entries across three layers (reference, pattern, decision). Gaps are captured as issue-ready drafts so the catalog grows from real usage rather than speculation. `/ultraplan-local` auto-discovers the architecture note — existing pipelines keep working unchanged.

 v1.7 self-verifying chain (preserved): a step may not be marked `completed` unless its manifest verifies. v1.8 Opus 4.7 literalism fixes (preserved): literal Step+Manifest template, forbidden narrative headers, schema self-check.
 
 Defense-in-depth security: plugin hooks block destructive commands and sensitive path writes, prompt-level denylist works in headless sessions, pre-execution plan scan catches dangerous commands before they run, scoped `--allowedTools` replaces `--dangerously-skip-permissions` in parallel sessions.
