## Title

    Proposed fix: [Claude Code Bash tool] 'task output swap refused (tasks dir moved or linked)' / 'Command killed: its output file was replaced or could no longer be verified'

## Body

    Recommended action: Upgrade to >= v2.1.260; restart with CLAUDE_CODE_TMPDIR set to a fresh dir nothing else manages; or remove the stray link/dir itself and restart.
    
    Option: Upgrade to >= v2.1.260; restart with CLAUDE_CODE_TMPDIR set to a fresh dir nothing else manages; or remove the stray link/dir itself and restart. [evidence: official_recommended_action]
    Applies when: Running Bash commands while something replaces/links entries under the Claude temp dir
    Steps:
    1. claude update (>= v2.1.260)
    2. export CLAUDE_CODE_TMPDIR=<fresh dir> and restart
    3. Remove the stray entry (not its target) under the temp project dir
    Expected: The error no longer appears.
