0.0.16 - Know thyself

The big one here is the autonomy extraction: docketeer's core is now a plain agent framework, and all the personality/inner-life stuff lives in docketeer-autonomy. You can build a boring chatbot without accidentally giving it an existential crisis.

Also in this release:

• docketeer-subprocess — a new executor for when you don't have bubblewrap (containers, macOS, etc.). Set DOCKETEER_EXECUTOR=subprocess. (#16)
• Search gets a catalog — SearchCatalog with named indices replaces the single shared index. MCP tool search is now semantic and works even for disconnected servers.
• Room context — rooms/{name}.md files auto-load into conversations, same as the people/ pattern already did.
• Tasks get their own rooms — scheduled tasks no longer share one conversation, so reverie isn't reading your nudge history and vice versa.
• edit_file tool — search-and-replace file editing, finally.
• Backend env vars are namespaced — DOCKETEER_ANTHROPIC_MODEL_SMART, DOCKETEER_DEEPINFRA_MODEL_SMART, etc., so they stop stepping on each other.
• Conversation digest in reverie — the agent actually knows what happened in your chats now before it goes off to think.
• Bunch of MCP fixes: string arguments, McpError handling, vault-backed secrets.
• Fixed the inference backend blowing up when the executor was None.
• Audit logs flush immediately, env schemas handle union types, bubblewrap gets a default PATH.
• Doc sync tests so READMEs can't drift from reality again.
