Use numeric indices for delta filenames, document limitations
...
- Delta files now named 0.zst, 1.zst etc — avoids path length issues
and ambiguous separator substitution; manifest maps index to path
- PLAN.md: document delta naming rationale
- PLAN.md: document cross-file deduplication limitation and possible
future approaches (zstd dictionary training, content-addressing, tar stream)

Add rsync exit code awareness + plan operation abstraction
...
- spawn.js: rsync() wrapper handles exit codes 0/24 as OK, 23 as fatal
- spawn.js: capture() accepts allowedExitCodes option
- run.js: all rsync calls go through rsync() wrapper
- PLAN.md: document planned operation abstraction refactor

Implement full run pipeline
...
- Phase 3: rsync with --itemize-changes captured, parsed into change list
- Phase 4: per-file zstd deltas written to DELTAS/tmp/N/files/
- Phase 5: manifest.json written, atomic rename tmp/N → N
- Phase 6: PEND promoted to PREV via rm+rename
- Dry-run prints all steps without executing
