feat(editor): add --catalog-by-name entry-name substring search

New utility complements --catalog-find (id-based,
single-id lookup) and --catalog-grep (catalog-header
label only) by searching every catalog file under a
directory tree for entries whose `name` field contains a
substring. Reports each hit as [WXXX] file id=N "name"
so the operator can find catalog entries by half-
remembered names — "find anything called Mark of the
Wild" hits all 5 rank entries across WBAB, "find Argent"
hits the WTBD tabard, etc.

Optional flags:
- --magic <WXXX>: limit search to one format family,
  same convention as --catalog-find.
- --ignore-case: lowercase both pattern and haystack
  before substring match.

Returns rc=0 on hits, rc=1 if no entries matched (so the
caller can `if --catalog-by-name ... ; then ...; fi`).
Skips files with unknown magic and files whose format
has no --info-* surface (asset formats like .wom).
Permission-denied subdirs skipped via
skip_permission_denied directory_options.

Closes the search triplet:
  --catalog-grep    catalog-header label
  --catalog-find    entry primary-key id
  --catalog-by-name entry name substring

CLI flag count 1169 -> 1170.
