*	refactor!: replace pack! macros with derive-based pipeline types	魏曹先生	3 days	1	-10/+12
\| \| \| \| \| \| \| \| \|	Remove the `pack!`, `pack_err!`, `pack_structural!`, and `pack_err_structural!` macros, replacing all pipeline type definitions with `#[derive(Grouped)]` and `#[derive(Grouped, Wrap)]` attributes. This changes the generated struct shape from named-field structs with an `inner` field to tuple structs accessed via `.0`, and removes the auto-generated `name` and `info` fields from error types.
*	feat(pkg-mgr): implement pkg-show command	魏曹先生	11 days	1	-0/+104
	Add `pkg-show` to display installed packages and their versions, removing its NOT_IMPL marker from help. Include internal commands to load enabled package paths and completion scripts.
