* refactor: remove managed/standalone mode distinction from codebase
Standalone mode is deprecated; managed mode is now the only mode.
Remove redundant "managed mode" qualifiers from comments, docs,
and error messages. Error strings now reference "database stores"
instead of "managed mode" for clarity.
* improve(onboard): streamline onboard process and env setup
Simplify onboard wizard, extract helpers to dedicated file,
update env example and entrypoint for default managed mode,
clean up prepare-env script, update i18n catalogs.
* fix(store): handle NULL JSONB columns in MCP server scan
Scan JSONB nullable columns (args, headers, env, settings) into *[]byte
instead of directly into json.RawMessage to prevent silent scan failures
when database values are SQL NULL. Also initialize result slices with
make() to return empty JSON arrays instead of null.
* fix(store): keep settings scanning direct since column is NOT NULL
Update sandbox image name, container prefix, Docker labels, and MCP client info
from 'openclaw' to 'goclaw' to match the repository project name.
Changes:
- internal/sandbox/sandbox.go: image and container prefix
- internal/sandbox/docker.go: Docker label and fallback prefix
- docker-compose.sandbox.yml: image reference in comments and env
- internal/mcp/manager_connect.go: MCP client info name
[]byte fields were base64-encoded during JSON serialization, causing
frontend TypeError when calling .join() on non-array values. Added
Array.isArray() guards in UI as defensive fallback.
