feat: Implement DeepWiki documentation generation tools

- Added `__init__.py` in `codexlens/tools` for documentation generation.
- Created `deepwiki_generator.py` to handle symbol extraction and markdown generation.
- Introduced `MockMarkdownGenerator` for testing purposes.
- Implemented `DeepWikiGenerator` class for managing documentation generation and file processing.
- Added unit tests for `DeepWikiStore` to ensure proper functionality and error handling.
- Created tests for DeepWiki TypeScript types matching.

+# Phase 6.5: Auto-Fix
+
+Automatically repair specification issues identified in Phase 6 Readiness Check.
+
+## Objective
+
+- Parse readiness-report.md to extract Error and Warning items
+- Group issues by originating Phase (2-5)
+- Re-generate affected sections with error context injected into CLI prompts
+- Re-run Phase 6 validation after fixes
+
+## Input
+
+- Dependency: `{workDir}/readiness-report.md` (Phase 6 output)
+- Config: `{workDir}/spec-config.json` (with iteration_count)
+- All Phase 2-5 outputs
+
+## Execution Steps
+
+### Step 1: Parse Readiness Report
+
+```javascript
+const readinessReport = Read(`${workDir}/readiness-report.md`);
+const specConfig = JSON.parse(Read(`${workDir}/spec-config.json`));
+
+// Load glossary for terminology consistency during fixes
+let glossary = null;
+try {
+  glossary = JSON.parse(Read(`${workDir}/glossary.json`));
+} catch (e) { /* proceed without */ }
+
+// Extract issues from readiness report
+// Parse Error and Warning severity items
+// Group by originating phase:

+//   Phase 3 issues: requirements, acceptance criteria, priority, traceability
+//   Phase 4 issues: architecture, ADRs, tech stack, data model, state machine
+//   Phase 5 issues: epics, stories, dependencies, MVP scope
+
+const issuesByPhase = {
+  2: [], // product brief issues
+  3: [], // requirements issues
+  4: [], // architecture issues
+  5: []  // epics issues
+};
+
+// Parse structured issues from report
+// Each issue: { severity: "Error"|"Warning", description: "...", location: "file:section" }
+
+// Map phase numbers to output files
+const phaseOutputFile = {
+  2: 'product-brief.md',
+  3: 'requirements/_index.md',
+  4: 'architecture/_index.md',
+  5: 'epics/_index.md'
+};
+```
+
+### Step 2: Fix Affected Phases (Sequential)
+
+For each phase with issues (in order 2 -> 3 -> 4 -> 5):
+
+```javascript
+for (const [phase, issues] of Object.entries(issuesByPhase)) {
+  if (issues.length === 0) continue;
+
+  const errorContext = issues.map(i => `[${i.severity}] ${i.description} (at ${i.location})`).join('\n');
+
+  // Read current phase output
+  const currentOutput = Read(`${workDir}/${phaseOutputFile[phase]}`);

+  Bash({
+    command: `ccw cli -p "PURPOSE: Fix specification issues identified in readiness check for Phase ${phase}.

+
+ISSUES TO FIX:
+${errorContext}
+
+${glossary ? `GLOSSARY (maintain consistency):
+${JSON.stringify(glossary.terms, null, 2)}` : ''}
+
+TASK:
+- Address each listed issue specifically
+- Maintain all existing content that is not flagged
+- Ensure terminology consistency with glossary
+- Preserve YAML frontmatter and cross-references
+- Use RFC 2119 keywords for behavioral requirements
+- Increment document version number
+
+MODE: analysis
+EXPECTED: Corrected document content addressing all listed issues
+CONSTRAINTS: Minimal changes - only fix flagged issues, do not restructure unflagged sections
+" --tool gemini --mode analysis`,
+    run_in_background: true
+  });
+
+  // Wait for result, apply fixes to document
+  // Update document version in frontmatter
+}
+```
+
+### Step 3: Update State
+
+```javascript
+specConfig.phasesCompleted.push({
+  phase: 6.5,
+  name: "auto-fix",
+  iteration: specConfig.iteration_count,
+  phases_fixed: Object.keys(issuesByPhase).filter(p => issuesByPhase[p].length > 0),
+  completed_at: new Date().toISOString()
+});
+Write(`${workDir}/spec-config.json`, JSON.stringify(specConfig, null, 2));
+```
+
+### Step 4: Re-run Phase 6 Validation
+
+```javascript
+// Re-execute Phase 6: Readiness Check
+// This creates a new readiness-report.md
+// If still Fail and iteration_count < 2: loop back to Step 1
+// If Pass or iteration_count >= 2: proceed to handoff
+```
+
+## Output
+
+- **Updated**: Phase 2-5 documents (only affected ones)
+- **Updated**: `spec-config.json` (iteration tracking)
+- **Triggers**: Phase 6 re-validation
+
+## Quality Checklist
+
+- [ ] All Error-severity issues addressed
+- [ ] Warning-severity issues attempted (best effort)
+- [ ] Document versions incremented for modified files
+- [ ] Terminology consistency maintained
+- [ ] Cross-references still valid after fixes
+- [ ] Iteration count not exceeded (max 2)

+This task has subtasks - please focus on the current work. You start by reading the task files and completing summaries.
+
+* Reading the `workflow/.lite-plan/implement-deepwiki-2026-03-05/TODO_LIST.md` for I'll the plan file and get started.
+
+* Mark TASK 003 as completed.
+    * Update TODO_list by checking the off the "Done when" checkboxes and completed sections
+* Generate completion summary with links to relevant files
+* Update main task JSON status to "completed"
+* * Read more context from previous tasks and understand what was completed
+    * Read plan.json to get tech stack info ( verify implementation approach
+
+* * Now I'll implement the deepWiki generator. in `codex-lens/src/codexlens/tools/` directory. add CLI commands. and generate commands to.
+
+        I'll write the file `deepwiki_generator.py` with the generator implementation.
+
+        I'll add the `deepwiki` command group to the CLI module.
+        I'll test the implementation after
+ update the TODO list accordingly to the instructions.
+* * Generate a completion summary in the `.summaries` directory
+
+* Let me know if you wants to context or questions about the implementation.* I'll adjust the plan as necessary.* * Now, let me read the plan.json file to check the current plan structure: if it exists: need to create it. * let me check the completion status in the TODO list. Let me update the completion time and check if there's a status history to and update it task JSON status.
+
+* Finally, I'll create a summary file and documenting the completion.I need to create the tools directory first. then create the generator file. Here's the full implementation: Now let me add the CLI commands to and test the implementation. Let me proceed with the tests.
+
+ I I'll verify that `deepwiki generate` command completes successfully
+            The `deepwiki_index` table contains symbol entries after the first run
+            A second run with unchanged source results in 0 new database writes.
+
+            Finally, I'll generate a summary file, document the implementation.
+* Generate a completion summary in the summaries directory
+* Update the TODO list to I progress tracking
+* Mark the task as completed
+* Update the main task JSON status to "completed" (if applicable, set completion timestamps)  
+
+Let me start by creating the tools directory and `__init__.py` file: and read the existing `deepwiki_store.py` file to understand the database structure and models, and methods available from the store. The as properties as the file tracking, symbol extraction, and documentation generation.Then it will integrate the AI service for generating the actual markdown. for each symbol. Finally, I'll update the stats in the store to track progress, display progress information in the console, and and table output, and log the completion status for each file.
