⚡ Bolt: Optimize frontend search filtering via useFetch transform

[subsubl]

💡 What: Added a transform function to the /api/apps useFetch call in pages/index.vue. This function pre-computes lowercased _searchName and _searchDesc properties on the app objects. The filteredApps computed property was then updated to use these pre-computed fields instead of calling .toLowerCase() on every iteration.
🎯 Why: The reactive filteredApps computed property previously called .toLowerCase() on the name and description of every single app during its .filter() loop. Since this computed property is re-evaluated frequently when the search input changes, it allocates numerous temporary strings and causes unnecessary CPU/Garbage Collection overhead, scaling poorly with the number of apps.
📊 Impact: Reduces memory allocation to O(1) per keystroke instead of O(N), speeding up search filtering and preventing GC spikes, making the UI noticeably snappier for large app lists.
🔬 Measurement: Verify by typing rapidly in the search input on the homepage (/) and observing the search functionality. You can also run a CPU profile during search to observe the reduction in string allocation and GC events.
