Refresh the v3.8.0 documentation set across API, setup, Docker,
environment, Fly.io, VM deployment, and troubleshooting guides.
Document the updated budget payload, management-auth requirements,
WebSocket bridge secret, Compose profiles, production deployment
details, and expanded Node support. Also update the OpenAPI catalog,
raise coverage thresholds to match the current baseline, and align
cloud-agent task route typing and schemas with the stricter runtime
behavior.
Centralize optional API key capability checks so dashboard forms and
provider schemas share the same rules, including keyless Pollinations
support and cloud-agent batch testing mode.
Also align auto-combo config on `routerStrategy`, keep legacy combo
reads compatible, preserve MCP routes as management APIs, narrow
`require-login` public access to readonly/bootstrap flows, and make
cloud-agent CORS reflect the request origin for credentialed requests.
Protect cloud agent task routes and model cooldown management endpoints
with management-session auth and consistent CORS handling.
Also align cloud agent API serialization with the dashboard, reuse the
provider connection schema for CLI key storage, and accept active OAuth
tokens when building virtual auto-combo candidates.
