release: v0.1.6

Fix slipstream bridge race condition, bump to v0.1.5

Remove os.path.exists() gates from _discover_socket() — always return
a path and let the connection attempt be the real test. Add retry with
backoff (0.1–2.0s) in _run_bridge_at() so the bridge survives the race
when Claude Code spawns slipstream and fcp-python in parallel.

Bump to v0.1.4 for PyPI publish with plugin.json fix

Fix bridge-only mode and registration, bump to v0.1.3

- Bridge-only mode: when SLIPSTREAM_SOCKET set + stdin not TTY, join bridge thread instead of mcp.run()
- handler_name: "fcp-py" → "fcp-python" (match binary name for plugin_manager discovery)
- capabilities: list → dict to match slipstream's FcpCapabilities struct
- start_bridge returns Thread for join in bridge-only mode

Fix slipstream socket discovery to match daemon's actual path

Bridge was checking /tmp/slipstream-{uid}/daemon.sock but the daemon
binds to {XDG_RUNTIME_DIR || TMPDIR || /tmp}/slipstream.sock.
Now matches slipstream-core's default_socket_path() exactly.

Bump to v0.1.1

Add agent_help to slipstream fcp.register call

Provides a reference card of all verbs, selectors, and example
slipstream CLI invocations so the daemon can serve dynamic help.
