gitignore: start a "tina sw" section with `vscode` settings

That is, in-mem history buffer files should have a `.hist` suffix (which
was added back instead of the weird `.h` change from the rebased
8352d89e).

I'm pretty sure we can afford the 3 extra chars if we're already
truncating to a max 16 char `key: str = f'{uuid[:8]}_{fqme_hash}'`, per
@goodboy's edit from the original key-truncation approach in the
original original @dnks patch: 75d8582b).
