 ## Versioning Rules

 - `bugfix` -> bump `+0.0.1`
 - `docs`, `maintenance`, and `refactor` do not bump by default unless the user explicitly wants a release

+- Compute the next version:
+  - `feature`: increment minor and reset patch to `0` (e.g. `0.41.2` → `0.42.0`)
+  - `bugfix`: increment patch only (e.g. `0.26.2` → `0.26.3`)
