[help wanted] write a ToolSpec for Aider

[rohitsux]

Aider is in v0.2 scope. It uses <project>/.aider.chat.history.md (Markdown) and <project>/.aider.llm.history (plaintext) instead of JSONL or SQLite. Special considerations:

• No hook system — capture is fs-watcher-only
• Markdown structure may not contain tool-call data; .llm.history may be needed for full coverage

Deliverable: a ToolSpec entry for Aider including the markdown line-section parser. Bring evidence (real session transcript fixture) showing what's available in each file.
