perf: optimize project search filtering workflow

[ash1shkumar]

📝 Description

This PR improves the project discovery workflow by introducing a reusable search preparation and filtering strategy for project lookups.

Previously, project search operations repeatedly traversed project names and tags during every filtering cycle. As project collections grow, repeated search computations can increase client-side processing overhead and reduce responsiveness during active user interactions.

Changes Implemented

• Introduced a reusable project filtering helper
• Added memoized search preparation using useMemo
• Precomputed searchable project metadata for more efficient lookups
• Reduced repeated project name and tag traversal operations
• Separated search preparation logic from rendering logic
• Improved maintainability and scalability of the project discovery workflow

Benefits

• Improved search responsiveness during user input
• Reduced repeated filtering computations
• Lower client-side processing overhead
• Cleaner separation of concerns
• Better scalability for larger project collections
• Easier future extension of search capabilities and filtering criteria

🎯 Type of Change

• Performance Improvement
• Refactoring
• Code Quality Improvement

✅ Testing

• Verified project search results remain unchanged
• Verified searches continue to match project names
• Verified searches continue to match project tags
• Verified empty search queries display all projects
• Verified project creation flow remains unaffected
• Verified UI rendering and filtering behavior remain consistent

Fixes #217
