* refactor: clarify compiler module boundaries - Rename backend, frontend, IR, and cache modules for explicit ownership. - Split native cache/vendor and frontend shared concerns into focused modules. - Expand compiler context names and refresh imports, tests, and documentation. * fix: preserve renamed compiler interfaces
