feat(pathf): add build-time type path resolution system

Add `mingling_pathf` sub-crate and `pathf` feature for automatic
resolution of Mingling type module paths at build time. Scans source
files, identifies macro invocations via pattern matchers, and generates
mapping files consumed by `gen_program!()`.

 1. **Build-time scanning**: `build.rs` traverses all `.rs` source files under `src/`, locating macro invocations such as `pack!`, `#[chain]`, `#[renderer]`, etc., via pattern matching.
 2. **Module inference**: The module path is inferred from the file's directory path (e.g., `src/app/sub.rs` → `app::sub`).
 3. **Reference tracking**: Following the chain of `mod use` re-exports (i.e., paths re-exported via `pub use` or `use`), the type name is resolved to the module path under which it is ultimately referenced.

 5. **Compile-time consumption**: `gen_program!()` reads this mapping file and uses the full paths for downcasting in the generated dispatch code.
