Major improvements to borgbackup configuration for better reliability and
maintainability:
**Shared staging directory:**
- Use single /btrfs-subvolumes directory (was /subvolumes-{onsite,offsite})
- Eliminates redundant path suffixes in archive structure
- Archive paths now semantic: /btrfs-subvolumes/srv-forgejo clearly indicates
BTRFS subvolume content without redundant backup job metadata
**Defense-in-depth protection:**
- Layer 1: Systemd ordering - offsite waits for onsite completion
- Layer 2: Self-healing preHook - auto-cleanup orphaned snapshots from
crashes/power loss
- Prevents cascading failures from race conditions or abnormal terminations
**Code quality improvements:**
- Extract subvolume lists to reduce duplication (DRY principle)
- Add /* sh */ syntax hints for proper editor highlighting
- Silent operation for consistency with existing hooks
- Improved readability with clearer comments and formatting
- All lines ≤ 100 characters
**Timing:**
- Offsite: *-*-* 00:15:00 (daily at 12:15 AM, waits for onsite)
- Onsite: hourly (unchanged)
