- src/lib/types.ts: message contract (both ANALYZE_TEXT shapes preserved), config/response types, storage-key constants. - src/lib/messaging.ts: single safeStorageGet/safeStorageSet/safeSendMessage/ isExtensionValid implementation replacing the three divergent copies in Options, Popup, and content. Content script keeps its refresh-toast behavior via an onContextInvalidated callback. - New '@lib' import alias (wxt force-overwrites '~' and '@' to srcDir, so those cannot point at ./src); wired in wxt.config, tsconfig, vitest. - tests/unit/messaging.test.ts: 14 unit tests over the wrappers.
