The dropdown showed positions ("3 / 16"); show the source name ("apple.ply")
instead. Loaders already stash the basename in mesh.metadata['file_name']
(mesh_io.py) and it survives the worker boundary (serialization.py forwards
metadata), so the node just reads it per mesh and returns a mesh_names array.
- Python: collect names (metadata['file_name'] -> metadata['name'] -> a
positional fallback) and add "mesh_names" to the UI arrays.
- JS: dropdown options are now built as real <option> elements with
textContent = name (falling back to "k / N"), so a filename cannot inject
markup. Also added a "Name" row to the info panel (escaped).
Verified: python compiles, JS parses, isolation lint still 0 errors.
