Filenames could exceed the OS limit: the slug was capped at 110 characters but the final
name is stem + slug, so a long source name pushed it past NAME_MAX (255 bytes on Linux, and
Windows caps the whole path near 260 without long paths). Names are now fitted to 160 bytes,
trimming both halves and appending a short hash of the full recipe when needed, so two
different recipes still never produce the same name. A path over 240 characters logs a
warning, since the folder above us is not ours to control.
Metadata now records what was applied rather than just that something was. The original
metadata is preserved untouched, and next to it:
bfs_surgery_summary one readable line, for viewers that know nothing about this tool
bfs_surgery tool, UTC timestamp, source filename and its sha256, the readable
recipe, the exact rules, and module counts (total/kept/dropped/scaled)
ss_output_name updated to the new filename
The sha256 matters more than the filename: it ties the result to the checkpoint it came from
even after either one is renamed.
