- POST /exec now accepts environmentId (UUID) and credentials (alias → UUID)
instead of raw payloads; resolves entities via EnvironmentService and
CredentialService before passing data to browserService.exec
- exec_code MCP tool updated with same schema: environmentId + credentials map
- CredentialModule imported into BrowserModule and McpModule
- docs(scenario): rewrite script runtime section for single context argument
- docs(mcp): update exec_code description to reflect new parameter shapes
- style: reorder imports across server source (formatter)
