fix(hako): Fix Chapter Path Parsing, Decrypt Protected Content, Format Notes, and Remove Suggestion Banners (#2270)

* fix(vi/Hako): fix chapter path parsing and decrypt protected chapter content

- Fix `parseNovel` extracting full URL instead of relative path for chapters.
- Implement decryption logic for protected chapter content (`#chapter-c-protected`) using XOR shuffle, base64 reverse, and plain base64 decoding.

* fix(vi/hako): format note tags, suggestion banners, and bump version to 1.1.1

- Format `[note(\d+)]` tags into HTML span/anchor tags for proper rendering (following the original website's logic)
- Remove recommendation/suggestion banners at the end of chapters
- Bump plugin version to 1.1.1
