Stop blocking the Node event loop on every chat send. The pi-claude-cli extension factory used to run two `execSync` probes (`claude --version`, `claude auth status`) on every `createFnAgent` call, which Fusion invokes per chat message — so each send froze every other dashboard API for a few seconds while the Claude CLI cold-started. Probes now run async via `spawn` and are memoized to once per process.
