Improve --generate performance with incremental builds (62s -> 2s)
Add mtime-based skip logic to avoid regenerating unchanged files:
- generate::fromgmi skips .gmi files where all outputs are newer
- template::_generate_file skips templates when output is fresh
- Diff-before-overwrite in templates, gemfeed, and notes indexes
to preserve mtimes and prevent cascading cache invalidation
- Global dependency check (.lastgen sentinel) for header/footer/CSS
- Job throttling via wait -n capped at nproc cores
- Add --force flag and FORCE_REBUILD env var to bypass skip logic
- Fix misleading atom feed "empty cache" log message
