## Title

    Proposed fix: [Claude Code hooks] Policy hook exits 1 or its script path is wrong: 'Failed with non-blocking status code:' and the tool call proceeds

## Body

    Recommended action: Use `exit 2` (or a JSON blocking decision) for policy hooks; verify the path and chmod +x; watch for the notice on first run.
    
    Option: Use `exit 2` (or a JSON blocking decision) for policy hooks; verify the path and chmod +x; watch for the notice on first run. [evidence: official_recommended_action]
    Applies when: PreToolUse/UserPromptSubmit command hook intended to block an action
    Steps:
    1. Change the hook to `exit 2` with the reason on stderr, or print a JSON decision
    2. Use an absolute path or ${CLAUDE_PROJECT_DIR}; consider exec form (`args`) to avoid shell quoting
    3. chmod +x the script
    4. Test manually: echo sample JSON | ./hook.sh; echo $?
    5. Enable --debug-file to see full stderr
    Expected: The error no longer appears.
