0.12.0

What's Changed

• Add Claude, Codex, and Cursor host plugin packages by @abnegate in #25
• (feat): learn from full history across every local agent by @abnegate in #26

/learn now collects every local harness by default, writes mapper shards in plan.json, and strips host chrome so an 800-session corpus is usable. since_last is recommended only after an unwindowed collect.
