Describe your change:

• Added a new algorithm file: JumpSearchOptimized.js

• Algorithm is an optimized version of Jump Search (reduces comparisons)
• Included detailed test cases for different scenarios (empty array, element not found, first/last element, etc.)

References:

• Wikipedia - Jump Search

Checklist:

• I have read CONTRIBUTING.md
• This pull request is all my own work — I have not plagiarized.
• This PR only changes one algorithm and its test file.
• All filenames follow the PascalCase convention (JumpSearchOptimized.js, JumpSearchOptimized.test.js).

Fixes: None (new algorithm addition)
