feat(editor): add --convert-m2-batch for bulk M2→WOM migration

Browse source 
Walks <srcDir> recursively for every .m2 file (case-insensitive,
including subdirs) and re-invokes --convert-m2 per file via a child
process so the existing single-file logic — AssetManager init, skin
file resolution, fromM2() pipeline — is reused verbatim. Per-file
[ok]/[FAIL] line streamed live; aggregate summary at the end.

Designed to migrate an entire creature/world model dump in one go.
This is the headline open-format conversion: every .m2 in a
proprietary data tree gets turned into a .wom open-format model. Pair
with the upcoming --convert-wmo-batch / --convert-blp-batch /
--convert-dbc-batch to migrate a complete extracted Data tree.

Verified discovery: 3 placeholder .m2 files (one in subdir, one
.M2 uppercase) found correctly; .txt skipped; all fail conversion as
expected for empty bytes; exit 1 on any failure. Brings command
count to 183.
