Alexander Payne 49ca4dad43 feat: Self-Edit MCP Tool (Phase 2.1)
Implements the Self-Edit MCP Tool that orchestrates the self-coding foundation:

## Core Features

1. **SelfEditTool** (src/tools/self_edit.py)
   - Complete self-modification orchestrator
   - Pre-flight safety checks (clean repo, on main branch)
   - Context gathering (codebase indexer + modification journal)
   - Feature branch creation (timmy/self-edit/{timestamp})
   - LLM-based edit planning with fallback
   - Safety constraint validation
   - Aider integration (preferred) with fallback to direct editing
   - Automatic test execution via pytest
   - Commit on success, rollback on failure
   - Modification journaling with reflections

2. **Safety Constraints**
   - Max 3 files per commit
   - Max 100 lines changed
   - Protected files list (self-edit tool, foundation services)
   - Only modify files with test coverage
   - Max 3 retries on failure
   - Requires user confirmation (MCP tool registration)

3. **Execution Backends**
   - Aider integration: --auto-test --test-cmd pytest --yes --no-git
   - Direct editing fallback: LLM-based file modification with AST validation
   - Automatic backend selection based on availability

## Test Coverage

- 19 new tests covering:
  - Basic functionality (initialization, preflight checks)
  - Edit planning (with/without LLM)
  - Safety validation (file limits, protected files)
  - Execution flow (success and failure paths)
  - Error handling (exceptions, LLM failures)
  - MCP registration

## Usage

    from tools.self_edit import register_self_edit_tool
    from mcp.registry import tool_registry

    # Register with MCP
    register_self_edit_tool(tool_registry, llm_adapter)

Phase 2.2 will add Dashboard API endpoints and UI.
