## Summary
**Step 1 of 2:** Implements the "acting on behalf of user" concept for
workflows and agents to prevent permission escalation and maintain
proper audit trails.
## Problem
Previously, workflows and agents would bypass permissions regardless of
who initiated them, allowing users to escalate their privileges by
triggering workflows that performed actions they couldn't do directly.
## Solution
### For Workflows
Introduced `WorkflowExecutionContext` service that determines execution
mode:
- **Manual triggers/test button**: Uses user's roleId for permissions,
user's identity for `createdBy`
- **Automated triggers** (cron, database events, webhooks): Bypasses
permissions, uses workflow identity
### For Agents
**In Chat:**
- Always act on behalf of the user
- Use user's roleId for permission checks
- Use user's identity for `createdBy`
# Step 1 vs Step 2
### ✅ Step 1 (This PR): Acting on Behalf Concept
- Introduced `isActingOnBehalfOfUser` boolean concept
- Single roleId used for permission checks (user's OR system bypass)
- `createdBy` field properly attributes actions to initiator
- Prevents permission escalation in user-initiated flows
### 🔜 Step 2 (Future): Multi-Role Permission Support
- Support role intersection: `{ intersection: ['roleA', 'roleB'] }`
- Support role union: `{ union: ['roleA', 'roleB', 'roleC'] }`
- Enable user+agent collaboration scenarios
- Update `WorkspaceEntityManager` and `WorkspaceDatasource` to handle
multiple roleIds
