feat(picker): add `mingling_support` feature and `is_flag` field

2026-07-14T18:41:14+00:00

Rename the `core` feature to `mingling_support` in `mingling_picker` and
propagate it through `mingling_picker_macros`.  Add the `is_flag` field
to `PickerTag` to indicate participation in parsing after a `--`
separator.  Remove empty `seek.rs` file.

feat: use `From` conversion instead of parsing string
