Improve handling of /tmp permissions and non-interactive mode:
1. /tmp permissions fix:
- Check current permissions before attempting to fix
- Display warning when fixing incorrect permissions (2775 -> 1777)
- Verify /tmp has permissions 1777 (sticky bit + world writable)
2. Non-interactive mode detection:
- Redirect stdin from /dev/null when running via sudo to prevent
read commands from hanging when stdin is not a TTY
- Add better error message in first_time_install.sh when non-interactive
mode is detected but ASSUME_YES is not set
- Check if stdin is a TTY before attempting interactive read
This fixes the issues identified in diagnostic output:
- /tmp permissions 2775 causing APT write failures
- read -p failing when stdin is not a TTY (curl | bash)
Fixes installation failures when running one-shot install via curl | bash.
