    Add summary comment when individual task completes
    
    Excellent! All linting passes. Let me create a final comprehensive
    summa
    
    Task **t-193.3: Add summary comment when individual task completes** is
    
    The feature was **already fully implemented** in the codebase. No
    code c
    
    The `addCompletionSummary` function in `Omni/Jr.hs` (lines 589-617)
    auto
    
    1. **Gathers commit information** when a task is accepted in review:
       - Git diff summary via `git show --stat` - Commit message via `git
       log -1 --format=%B` - List of modified files via `git diff-tree`
    
    2. **Generates an LLM summary** using the `llm` CLI tool:
       - Passes task ID, commit message, files, and diff to the LLM -
       Requests a 2-4 sentence professional summary - Includes what was
       accomplished and key files modified
    
    3. **Adds the summary as a task comment** using `TaskCore.addComment`:
       - Format: `## Completion Summary\n\n{llm-generated-text}`
    
    The function is called in two places: - **Line 427**: After auto-review
    accepts a task (tests pass) - **Line 508**: After interactive/human
    review accepts a task
    
    ✅ **All tests pass**: `bild --test Omni/Jr.hs` - 12/12 tests
    successful ✅ **Linting passes**: Both ormolu and hlint pass with
    no issues ✅ **Dependencies configured**: `llm` tool is included in
    build metadata
    
    ✅ Trigger after accepting task in review ✅ What files were
    modified ✅ Brief description of changes from LLM ✅ Use LLM to
    generate summary from diff ✅ Add as comment via TaskCore.addComment
    
    The implementation is working as specified and ready for use.
