Add document standards, quality gates, and templates for team lifecycle phases

- Introduced `document-standards.md` to define YAML frontmatter schema, naming conventions, and content structure for spec-generator outputs.
- Created `quality-gates.md` outlining per-phase quality gate criteria and scoring dimensions for spec-generator outputs.
- Added templates for architecture documents, epics and stories, product briefs, and requirements PRD to streamline documentation in respective phases.

+# Planner — Phase 2-4
+
+## Phase 1.5: Load Spec Context (Full-Lifecycle)
+
+If `<session-folder>/spec/` exists → load requirements/_index.md, architecture/_index.md, epics/_index.md, spec-config.json. Otherwise → impl-only mode.
+
+**Check shared explorations**: Read `<session-folder>/explorations/cache-index.json` to see if analyst already cached useful explorations. Reuse rather than re-explore.
+
+## Phase 2: Multi-Angle Exploration
+
+**Objective**: Explore codebase to inform planning.
+
+**Complexity routing**:
+
+| Complexity | Criteria | Strategy |
+|------------|----------|----------|
+| Low | < 200 chars, no refactor/architecture keywords | ACE semantic search only |
+| Medium | 200-500 chars or moderate scope | 2-3 angle explore subagent |
+| High | > 500 chars, refactor/architecture, multi-module | 3-5 angle explore subagent |
+
+For each angle, use CLI exploration (cache-aware — check cache-index.json before each call):
+
+```
+Bash({
+  command: `ccw cli -p "PURPOSE: Explore codebase from <angle> perspective to inform planning
+TASK: • Search for <angle>-specific patterns • Identify relevant files • Document integration points
+MODE: analysis
+CONTEXT: @**/* | Memory: Task keywords: <keywords>
+EXPECTED: JSON with: relevant_files[], patterns[], integration_points[], recommendations[]
+CONSTRAINTS: Focus on <angle> perspective" --tool gemini --mode analysis --rule analysis-analyze-code-patterns`,
+  run_in_background: false
+})
+```
+
+## Phase 3: Plan Generation
+
+**Objective**: Generate structured implementation plan.
+
+| Complexity | Strategy |
+|------------|----------|
+| Low | Direct planning → single TASK-001 with plan.json |
+| Medium/High | cli-lite-planning-agent with exploration results |
+
+**CLI call** (Medium/High):
+
+```
+Bash({
+  command: `ccw cli -p "PURPOSE: Generate structured implementation plan from exploration results
+TASK: • Create plan.json with overview • Generate TASK-*.json files (2-7 tasks) • Define dependencies • Set convergence criteria
+MODE: write
+CONTEXT: @<session-folder>/explorations/*.json | Memory: Complexity: <complexity>
+EXPECTED: Files: plan.json + .task/TASK-*.json. Schema: ~/.ccw/workflows/cli-templates/schemas/plan-overview-base-schema.json
+CONSTRAINTS: 2-7 tasks, include id/title/files[].change/convergence.criteria/depends_on" --tool gemini --mode write --rule planning-breakdown-task-steps`,
+  run_in_background: false
+})
+```
+
+**Spec context** (full-lifecycle): Reference REQ-* IDs, follow ADR decisions, reuse Epic/Story decomposition.
+
+## Phase 4: Submit for Approval
+
+1. Read plan.json and TASK-*.json
+2. Report to coordinator: complexity, task count, task list, approach, plan location
+3. Wait for response: approved → complete; revision → update and resubmit
+
+**Session files**:
+```
+<session-folder>/explorations/          (shared cache)
++-- cache-index.json
++-- explore-<angle>.json
+
+<session-folder>/plan/
++-- explorations-manifest.json
++-- plan.json
++-- .task/TASK-*.json
+```
+
+## Error Handling
+
+| Scenario | Resolution |
+|----------|------------|
+| CLI exploration failure | Plan from description only |
+| CLI planning failure | Fallback to direct planning |
+| Plan rejected 3+ times | Notify coordinator, suggest alternative |
+| Schema not found | Use basic structure |
+| Cache index corrupt | Clear cache, re-explore all angles |
