Encrypt (Options) and decrypt (background) now share one module; wire
format unchanged. Tests include fixtures proving values encrypted by the
old inline Options code still decrypt, plus tamper/wrong-key cases. The
module documents the honest threat model (key co-located with ciphertext
= obfuscation, not encryption).

- 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.
