The legacy `parser` feature and its module tree (`mingling::parser`,
`Argument`, `Picker`, `Pickable`, etc.) have been fully removed and
replaced by the `picker` feature powered by `arg-picker`.

BREAKING CHANGE: Remove `parser` feature and use `picker` instead.
Migration guide: Replace `features = ["parser"]` with
`features = ["picker"]` and update API usage per the provided table.

Dispatchers are now always registered at compile time, removing the
`with_dispatcher` / `with_dispatchers` methods and the
`PathfinderConfig` API. The `dispatch_tree` feature now only controls
the matching strategy (trie vs linear list).

Add the Arborium JS library header to the documentation build via
RUSTDOCFLAGS and docs.rs metadata so generated docs include the
interactive Arborium components.

Add convenience presets (`mini`, `advanced`, `full`, `build_advanced`,
`build_full`) to `mingling/Cargo.toml` and document them in both
English and Chinese feature docs. Update getting-started guides to
reflect the new default `core`/`macros` features.

Update all references across docs, examples, and configuration files to
use the shorter `extras` feature name.

Replace the `builds` feature with `build` across the crate, keeping
a backward-compatible alias for the old name.  Update all internal
visibility from `#[doc(hidden)] pub mod` to `pub(crate) mod` and
reorganize the `__private` module into a dedicated `private.rs`.

Add `docs_rs` feature flag to enable docs.rs-specific configuration,
including `--generate-link-to-definition` and logo display.

Include the feature in build scripts, editor settings, and feature
constants for consistent documentation generation.

methods

Deprecate `ShellContext` methods `filling_argument_first`,
`filling_argument`, `typing_argument`, `strip_typed_argument`, and
`get_typed_arguments` when the `picker` feature is active, as they
do not work under all `ParserStyle` settings.

Add `#![allow(deprecated)]` to the affected modules to suppress
warnings from internal usage.

BREAKING CHANGE: Remove `mingling_support` feature from arg-picker
crate. The
`EntryPicker` trait and `corebind` module are now part of the mingling
crate
directly, and `build_pattern1` is now a public method.
