Claude 965dbf27eb Add disk space error handling utilities for better UX when disk is full ...

When disk space runs out, Claude Code can become unresponsive or crash without
clear feedback. This adds:

- New disk_space_utils.py module with:
  - ENOSPC error detection (errno 28)
  - User-friendly warning messages with remediation steps
  - Disk space availability checking
  - Safe file write/append helpers

- Updated security_reminder_hook.py to:
  - Check disk space at startup and warn users proactively
  - Detect disk space errors during state file operations
  - Provide actionable guidance when disk issues are detected

The warnings include specific remediation steps (df -h, cleaning /tmp,
emptying trash, docker prune) to help users resolve the issue.
