TASK: Fix Trello Card #908 Google Docs Permissions

OBJECTIVE:
- Fetch Trello card 6a1d64277ddbf0d220035bbb (Card #908 CINIK)
- Parse Google Docs links from description (languages: en, it, de, es, etc., but NOT fr)
- For each non-FR doc: call python3 /opt/automator/cinik-writer-transtor/files/_share_fix.py share <docId>
- Return: cardShort=908, results (lang+role+changed), allWriter (true if all="writer"), problems (any failures)

TOOLS LOADED:
✓ mcp__trello__get_card (loaded via ToolSearch)

BLOCKER:
This is a subagent. Subagents cannot invoke MCP tools directly. Need parent agent to:
1. Call: mcp__trello__get_card(cardId="6a1d64277ddbf0d220035bbb", includeMarkdown=true)
2. Pass card data (JSON with "desc" field) to this subagent
3. Subagent will then: parse desc → extract lang:docId pairs → run _share_fix.py for each non-FR

NEXT: Parent must invoke mcp__trello__get_card and re-invoke this task with card data
