*	refactor!: replace pack! macros with derive-based pipeline types	魏曹先生	45 hours	1	-15/+20
\| \| \| \| \| \| \| \| \|	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(config): add cfg --pair flag and refactor config path	魏曹先生	10 days	1	-0/+110
	Add `--pair` flag to output config values as `"key" = "value"` pairs, and provide escaped formatting for display. Move config path resolution to a helper function and expose the underlying hash map for rendering and completion.
