I think the new tests are good & look like they're passing so my edits to tags.scm are WAI? My first time touching tree-sitter so please hand-hold if that's wrong 🙏

I think backticked names were already captured, but adding a test here since that's a useful edge case to keep tabs on.

I wonder if shorthand-lambdas should be included as well, but decided against it as out-of-scope for this PR for now, WDYT?

Friendly ping! If you're swamped that's fine, just reminding before I forget about it myself :)
