* feat(pico): add pico_client outbound WebSocket channel
Add a client-mode counterpart to the existing pico server channel.
pico_client connects to a remote Pico Protocol WebSocket server,
enabling picoclaw to bridge messages with external Pico-compatible
services.
Includes config, factory registration, manager wiring, 8 unit tests,
and a minimal echo-server example for interactive testing.
* fix(pico): address PR #1198 review — goroutine leak, race, auth
- Add per-connection context cancel to picoConn to prevent pingLoop
goroutine leak on disconnect
- Re-acquire mutex in StartTyping stop closure to avoid stale conn race
- Remove query-param token auth from echo server (header-only)
- Move ListenAndServe to main goroutine where log.Fatal is safe

* fix: replace ConsumeInbound with InboundChan select in client test
MessageBus does not expose a ConsumeInbound method. Use a select on
InboundChan() with context cancellation, matching the pattern used in
the bus package tests.
