⚡ Bolt: Optimize version comparison and list sorting collation

💡 What:

  • Optimized compareVersions in src/lib/format.ts to use a zero-allocation single-pass index scanner instead of string .split(".") and array .map(...).
  • Memoized Intl.Collator instance in src/pages/InstalledPage.tsx to prevent creating new Intl.Collator instances on every item comparison during list sorting.
  • Added comprehensive unit tests in src/lib/format.test.ts.

🎯 Why:
Sorting mod release lists and installed mod lists runs comparison callbacks frequently. Allocating arrays or creating collation objects inside sorting callbacks causes garbage collection overhead on large mod lists.

📊 Impact:

  • Eliminates temporary array allocations during version sorting (e.g. release dropdowns, dependency plan sorting, changelog filtering).
  • Reduces CPU overhead when sorting installed mods by name.

PR created automatically by Jules for task 3795807960009025533 started by @TheDragonSoft

- Replace string split and map allocations in compareVersions with a zero-allocation single-pass scanner.
- Reuse a memoized Intl.Collator instance in InstalledPage to prevent repeated collator allocations on list sorting.
- Add unit test suite for format and version comparison utilities.
