Add builtin-commands feature with init-deep command and disabled_commands config option

- New src/features/builtin-commands/ module with CommandDefinition loader
- Implements init-deep command for hierarchical AGENTS.md knowledge base generation
- Adds BuiltinCommandName and BuiltinCommandNameSchema to config
- Integrates builtin commands loader into main plugin with proper config merging
- Supports disabling specific builtin commands via disabled_commands config array

+export const INIT_DEEP_TEMPLATE = `# Initialize Deep Knowledge Base
+
+Generate comprehensive AGENTS.md files across project hierarchy. Combines root-level project knowledge (gen-knowledge) with complexity-based subdirectory documentation (gen-knowledge-deep).
+
+## Usage
+
+\`\`\`
+/init-deep                      # Analyze and generate hierarchical AGENTS.md
+/init-deep --create-new         # Force create from scratch (ignore existing)
+/init-deep --max-depth=2        # Limit to N directory levels (default: 3)
+\`\`\`
+
+---
+
+## Core Principles
+
+- **Telegraphic Style**: Sacrifice grammar for concision ("Project uses React" → "React 18")
+- **Predict-then-Compare**: Predict standard → find actual → document ONLY deviations
+- **Hierarchy Aware**: Parent covers general, children cover specific
+- **No Redundancy**: Child AGENTS.md NEVER repeats parent content
+
+---
+
+## Process
+
+<critical>
+**MANDATORY: TodoWrite for ALL phases. Mark in_progress → completed in real-time.**
+</critical>

+\`\`\`

+
+## Phase 1: Parallel Project Analysis
+
+**Mark "p1-analysis" as in_progress.**
+
+Launch **ALL tasks simultaneously**:
+
+<parallel-tasks>
+
+### Structural Analysis (bash - run in parallel)
+\`\`\`bash
+# Task A: Directory depth analysis
+find . -type d -not -path '*/\\.*' -not -path '*/node_modules/*' -not -path '*/venv/*' -not -path '*/__pycache__/*' -not -path '*/dist/*' -not -path '*/build/*' | awk -F/ '{print NF-1}' | sort -n | uniq -c

+# Task D: Existing knowledge files
+find . -type f \\( -name "AGENTS.md" -o -name "CLAUDE.md" \\) -not -path '*/node_modules/*' 2>/dev/null
+\`\`\`
+
+### Context Gathering (Explore agents - background_task in parallel)
+
+\`\`\`
+background_task(agent="explore", prompt="Project structure: PREDICT standard {lang} patterns → FIND package.json/pyproject.toml/go.mod → REPORT deviations only")
+
+background_task(agent="explore", prompt="Entry points: PREDICT typical (main.py, index.ts) → FIND actual → REPORT non-standard organization")
+
+background_task(agent="explore", prompt="Conventions: FIND .cursor/rules, .cursorrules, eslintrc, pyproject.toml → REPORT project-specific rules DIFFERENT from defaults")
+
+background_task(agent="explore", prompt="Anti-patterns: FIND comments with 'DO NOT', 'NEVER', 'ALWAYS', 'LEGACY', 'DEPRECATED' → REPORT forbidden patterns")
+
+background_task(agent="explore", prompt="Build/CI: FIND .github/workflows, Makefile, justfile → REPORT non-standard build/deploy patterns")
+
+background_task(agent="explore", prompt="Test patterns: FIND pytest.ini, jest.config, test structure → REPORT unique testing conventions")
+\`\`\`
+
+</parallel-tasks>
+
+**Collect all results. Mark "p1-analysis" as completed.**
+
+---
+
+## Phase 2: Complexity Scoring & Location Decision
+
+**Mark "p2-scoring" as in_progress.**
+
+### Scoring Matrix
+
+| Factor | Weight | Threshold |
+|--------|--------|-----------|
+| File count | 3x | >20 files = high |
+| Subdirectory count | 2x | >5 subdirs = high |
+| Code file ratio | 2x | >70% code = high |
+| Unique patterns | 1x | Has own config |
+| Module boundary | 2x | Has __init__.py/index.ts |
+
+### Decision Rules
+
+| Score | Action |
+|-------|--------|
+| **Root (.)** | ALWAYS create AGENTS.md |
+| **High (>15)** | Create dedicated AGENTS.md |
+| **Medium (8-15)** | Create if distinct domain |
+| **Low (<8)** | Skip, parent sufficient |
+
+### Output Format
+
+\`\`\`
+AGENTS_LOCATIONS = [
+  { path: ".", type: "root" },
+  { path: "src/api", score: 18, reason: "high complexity, 45 files" },
+  { path: "src/hooks", score: 12, reason: "distinct domain, unique patterns" },
+]
+\`\`\`
+
+**Mark "p2-scoring" as completed.**
+
+---
+
+## Phase 3: Generate Root AGENTS.md
+
+**Mark "p3-root" as in_progress.**
+
+Root AGENTS.md gets **full treatment** with Predict-then-Compare synthesis.

+
+## Phase 4: Generate Subdirectory AGENTS.md
+
+**Mark "p4-subdirs" as in_progress.**
+
+For each location in AGENTS_LOCATIONS (except root), launch **parallel document-writer agents**:
+
+\`\`\`typescript
+for (const loc of AGENTS_LOCATIONS.filter(l => l.path !== ".")) {
+  background_task({
+    agent: "document-writer",
+    prompt: \\\`
+      Generate AGENTS.md for: \${loc.path}
+      
+      CONTEXT:
+      - Complexity reason: \${loc.reason}
+      - Parent AGENTS.md: ./AGENTS.md (already covers project overview)
+      
+      CRITICAL RULES:
+      1. Focus ONLY on this directory's specific context
+      2. NEVER repeat parent AGENTS.md content
+      3. Shorter is better - 30-80 lines max
+      4. Telegraphic style - sacrifice grammar
+      
+      REQUIRED SECTIONS:
+      - OVERVIEW (1 line: what this directory does)
+      - STRUCTURE (only if >5 subdirs)
+      - WHERE TO LOOK (directory-specific tasks)
+      - CONVENTIONS (only if DIFFERENT from root)
+      - ANTI-PATTERNS (directory-specific only)
+      
+      OUTPUT: Write to \${loc.path}/AGENTS.md
+    \\\`
+  })
+}
+\`\`\`
+
+**Wait for all agents. Mark "p4-subdirs" as completed.**
+
+---
+
+## Phase 5: Review & Deduplicate
+
+**Mark "p5-review" as in_progress.**
+
+### Validation Checklist
+
+For EACH generated AGENTS.md:
+
+| Check | Action if Fail |
+|-------|----------------|
+| Contains generic advice | REMOVE the line |
+| Repeats parent content | REMOVE the line |
+| Missing required section | ADD it |
+| Over 150 lines (root) / 80 lines (subdir) | TRIM |
+| Verbose explanations | REWRITE telegraphic |
+
+### Cross-Reference Validation
+
+\`\`\`
+For each child AGENTS.md:
+  For each line in child:
+    If similar line exists in parent:
+      REMOVE from child (parent already covers)
+\`\`\`
+
+**Mark "p5-review" as completed.**

+## Anti-Patterns for THIS Command
+
+- **Over-documenting**: Not every directory needs AGENTS.md
+- **Redundancy**: Child must NOT repeat parent
+- **Generic content**: Remove anything that applies to ALL projects
+- **Sequential execution**: MUST use parallel agents
+- **Deep nesting**: Rarely need AGENTS.md at depth 4+
+- **Verbose style**: "This directory contains..." → just list it`
