feat(shared): expose pi-mono connector catalog to renderer

Add @shared/connector-catalog.ts mirroring the 26-entry pi-mono catalog
from src/main/connector-definitions so renderer can drive provider UI
without importing main-process modules. Widen connectorInputSchema to
accept the new ConnectorId union (5 OAuth + 18 API key + 3 cloud).
