OAuth tokens from ccr_inference (Cowork/CCD scheduled tasks) accumulate without cleanup

Description

OAuth tokens created by Claude Desktop's background Claude Code Runner sessions (ccr_inference) accumulate on the account without being revoked when the background session ends. Over normal usage, 30+ stale tokens pile up visible at https://claude.ai/settings/claude-code.

Steps to Reproduce

1. Enable coworkScheduledTasksEnabled and ccdScheduledTasksEnabled in Claude Desktop config (both default to true)
2. Use Claude Desktop normally for a few days
3. Visit https://claude.ai/settings/claude-code
4. Observe 30+ ccr_inference sessions listed, most from completed/dead background runs

Expected Behavior

Background ccr_inference sessions should revoke their OAuth token when the session completes or is cleaned up. The settings page should show only active sessions.

Actual Behavior

Every background session creates a new OAuth token that persists indefinitely. No automatic cleanup occurs. There is also no "Revoke All" button to bulk-clear them.

Environment

• Claude Desktop v1.1.8359
• Claude Code v2.1.78
• macOS 15 (Darwin 25.3.0)

Additional Context

• No revoke all option exists on the settings page — users must click through each one individually
• The accumulation is confusing and looks like session stealing to users who notice it
• Feature request: either auto-revoke on session end, or add a "Revoke All" bulk action
