Server-side (primary): Apply redact.Text/InputMap on task message
content, output, and input fields before DB persistence and WebSocket
broadcast. Extended redact package with GitLab tokens, JWTs, connection
strings, and PASSWORD/SECRET/TOKEN env var patterns.
Frontend (fallback): redactSecrets utility mirrors server patterns,
applied in buildTimeline and ToolCallRow render as a safety net.
- Add redact package to detect and mask secrets (AWS keys, private keys,
API tokens, bearer tokens, credentials, home paths) in agent output
before posting as comments in TaskService
- Enforce agent visibility on issue assignment: private agents can only
be assigned by their owner or workspace admins
- Add visibility picker (workspace/private) to CreateAgentDialog,
default to private
- Grey out unassignable private agents in the assignee picker with
lock icon indicator
