[BUG] Cowork scheduled tasks reference ephemeral session upload path instead of persistent skill file path

What's Wrong?

When a scheduled task fires, the <scheduled-task> system tag passes a file attribute pointing to a session-specific uploads path (e.g. /sessions/<session-id>/mnt/uploads/SKILL.md). Because each scheduled task run starts a fresh session, this path never exists — causing the task to fail on every execution.

What Should Happen?

The file attribute in the <scheduled-task> tag should point to the persistent skill file location: ~/Documents/Claude/Scheduled/<taskId>/SKILL.md — not the ephemeral session uploads folder.

Error Messages/Logs

File does not exist: /sessions/<session-id>/mnt/uploads/SKILL.md

The persistent skill file exists at: ~/Documents/Claude/Scheduled/email-triage-midday/SKILL.md

Steps to Reproduce

1. Create a scheduled task via the Cowork scheduled tasks tool
2. 2. Wait for it to fire automatically on its cron schedule (or trigger it manually)
3. 3. Claude attempts to read the SKILL.md file at the path provided in the file attribute of the <scheduled-task> tag
4. 4. File is not found — task fails with: "File does not exist: /sessions/<session-id>/mnt/uploads/SKILL.md"

Note: The actual SKILL.md exists at ~/Documents/Claude/Scheduled/<taskId>/SKILL.md but the system tag points to the wrong path.
