The bridge was hard-wired to one worker profile. Config now takes a 'workers'
map keyed by profile name plus 'defaultWorker'; WorkerService holds the map and
gains spawn(profile) (spawn() uses the default). Selection threads through the
surfaces: REST POST /workers ?profile= / {"profile":…} + GET /profiles; MCP
bridge_spawn {profile?} + new bridge_profiles. Each profile's base_url is
guard-checked independently, so gx10 and ollama can run side by side and you
address each worker by its returned sessionId. Backward-compatible: the legacy
singular 'worker:' block still loads as a one-entry profile map.
