0.2.0

First release driven by real use.

• GET /models: the live omp catalog for client model pickers
• Fixed: a quiet child process locked its actor dead — stdout reading now runs off the actor, so request timeouts can fire and a server that stops talking can never wedge a route
• Fixed: install.sh restarts a running service after a rebuild, and reuses the password an existing claude-bridge or opencode-serve config already uses instead of minting a new one
• Discovery-ready: answers scans on port 4099 with agent "omp"
