Changes Made

roboco/agents/base.py - Added proper workflow methods:
  - _qa_pass(task_id, qa_notes) - Calls /pass-qa endpoint
  - _qa_fail(task_id, qa_notes, issues) - Calls /fail-qa endpoint
  - _docs_complete(task_id, doc_notes?) - Calls /docs-complete endpoint
  - Marked old _mark_needs_revision, _mark_awaiting_documentation, _mark_awaiting_pm_review as DEPRECATED

  roboco/agents/qa.py - Fixed verdict phase:
  - Now uses _qa_pass() instead of _mark_awaiting_documentation()
  - Now uses _qa_fail() instead of _mark_needs_revision()
  - Properly passes QA notes and issue lists

  roboco/agents/documenter.py - Fixed submit phase:
  - Now uses _docs_complete() instead of _mark_awaiting_pm_review()
  - Properly passes documentation summary as notes

 Single source of truth for agent roles, teams, and cell memberships.

+PERMISSION ARCHITECTURE
+-----------------------
+The system uses TWO complementary permission layers:
+
+1. MCP Layer (this module - agents_config.py):
+   - Controls which MCP tools agents can access
+   - Uses role-based helper functions: can_create_tasks(), can_cancel_tasks(), etc.
+   - Works with agent slugs/UUIDs directly
+   - Determines tool visibility at MCP server registration time
+
+2. API Layer (roboco/services/permissions.py):
+   - Controls fine-grained API endpoint access
+   - Uses TaskAction enum and PermissionService class
+   - Works with AgentContext and Team enums
+   - Validates at request time with team-scoped checks
+
+Both layers derive from the same source data (role definitions here) but serve
+different purposes. MCP is coarse-grained (tool-level), API is fine-grained
+(action + team context).
