Add in some dev deps for @goodboy

Namely since i use `xonsh` for a main shell, this includes adding it as
well as related tooling.

Some other stuff retained from `poetry` days,
- add usage-comments around various (optional) deps.
- add toml section separator lines.
- go with 2-space indent.
- add comment on `trio>0.27` needed for py3.13+
