- Add CLAWDIS_GATEWAY_PASSWORD to launchd plist environment
- Read password from gateway.remote.password config in client
- Fix Swift 6.2 sending parameter violations in config save functions
- Add password parameter to GatewayConnection.Config type
- GatewayChannel now sends password in connect auth params
- GatewayEndpointStore and GatewayLaunchAgentManager read password from config
- CLI gateway client reads password from remote config and env
The CLI client (callGateway) now reads password from:
1. opts.password (explicit parameter)
2. CLAWDIS_GATEWAY_PASSWORD env var (NEW)
3. remote.password from config
This allows CLI commands like doctor/health to authenticate
without needing a --password flag when the env var is set.
Fixes auth issues for users with password-protected gateways.
