refactor: move resource/IO root modules under io/
Relocate three root-level modules into io/, where they belong by concern: - update_check.rs -> io/update_check.rs (its own doc-comment notes it mirrors how crate::io wraps blocking calls in async). - patterns.rs, linetypes.rs -> io/ (standard resource catalogs parsed from asset files and populated into the document — IO-shaped work). Fix the moved files' include_str! paths (one level deeper), add the mod declarations to io/mod.rs, drop them from lib.rs/main.rs, and re-point all crate:: references to crate::io::. No behavior change. Co-Authored-By: Claude Opus 4.8 <[email protected]>
