v4.1.5 — attestor teardown (zero-question uninstall)

attestor teardown — the one-command, zero-question reverse of attestor quickstart. Removes the postgres + neo4j + pinecone containers, ~/.attestor config, the ./.mcp.json MCP entry, and the lifecycle hooks (content-matched on attestor hook — never other tools').

• Data-safe by default: Docker named volumes are kept, so a later quickstart reconnects to the same memories.
• --purge deletes the volumes (wipes all stored memories); --dry-run previews.
• Leaves the pipx package + plugin alone (separate surfaces) and prints their removal commands.
• /uninstall-attestor now leads with this quick path, keeping the 6-surface manual procedure as the fallback.

Usage: attestor teardown · attestor teardown --purge · attestor teardown --dry-run
