refactor(mingling_picker): move parse result out of requirement and into

2026-07-13T18:17:33+00:00

pattern

BREAKING CHANGE: `PickerRequirement` no longer stores a `PickerResult`.
Parsed results are now held in the `PickerPattern` structs.
The `result`, `result_mut`, `set_result`, `reset_result`, and
`with_result` methods on `PickerRequirement` have been removed.
The `Picker::pick` method is introduced to begin a pattern definition.

feat(picker): add core trait, types, and builder macro for argument

parsing

Implement the foundational `mingling_picker` library along with its
companion
`mingling_picker_macros` crate. The picker provides:

- `Pickable` trait for parsing types from raw strings
- `PickerResult` enum modeling parse outcomes
- `Picker` struct for storing and indexing command-line arguments
- `PickerRequirement` struct for declarative parameter definitions
- `PickerPattern` family (1..32) of typed pattern structs via the
  `internal_repeat` proc macro
- `req!` proc macro as a succinct builder for `PickerRequirement`

Re-export `mingling_picker::macros::*` from the `mingling` crate when
the
`picker` feature is enabled, replacing the previous wildcard re-export
of
`mingling_macros`.
