fix: expand ~ in split command directory argument (#361)

brookewhatnall · claude · web-flow · commit dc143471bcb8 · 2026-04-11T23:14:28.000-07:00
Path("~/foo") does not expand tilde on its own, causing
`mempalace split ~/some/dir` to silently find no files.

Fix by calling .expanduser().resolve() in both places the
path is constructed: cmd_split in cli.py (defensive, at the
CLI boundary) and main() in split_mega_files.py (the root cause).
