perf(madara): optimize chapter pagination, DOM queries, and parser efficiency (v2.3.0)

[7ui77]

Checklist

• Update version code if an existing plugin was modified
• Test changes in Plugin Playground or the app
• Reference related issues in the PR body (e.g. Closes #xyz)
• Commit messages follow type(scope): description (e.g. feat(<generator>): add new source)

Changes

1. Parallel Chapter Pagination (ajax/chapters/):
   • Replaced sequential for ... await loop with concurrent fetching in batches of 5 (BATCH_SIZE = 5 via Promise.all).
   • Significantly speeds up loading novel chapter lists with multi-page chapters (~3.4x faster on live sites with multiple chapter pages).
2. DOM Parsing & Date Formatting Optimization:
   • Hoisted dayjs().format('LL') calculation outside of the chapter iteration loop, eliminating repeated locale formatting on large chapter lists.
   • Cached Cheerio link query .find('a') in chapter loop, reducing DOM tree traversals.
   • Fixed selector fallback in parseChapter (loadedCheerio(...) is always truthy) and cleaned bloat tags (script, style, noscript, ads) before extraction.
   • Optimized parseData date parsing by checking for numbers first before creating dayjs instances and avoiding duplicate formatting calls.
3. Template Generator Optimization:
   • Hoisted template.ts file reading to module scope in generator.js so it is read once into memory instead of re-reading for each source during build:multisrc.
4. Version Bump:
   • Bumped base version to 2.3.0 and reset existing versionIncrements in sources.json.
