💡 What: Implements a client-side and SSR-safe cache for domain name searches using a module-level Svelte context. Limits cache size to 500 items and adds a TTL of 5 minutes. Clears debounceTimer in an onDestroy block.
🎯 Why: Prevents redundant network requests and speeds up the UI for users checking multiple domains or re-typing previous queries. Reduces memory leaks from unmounted components.
📊 Impact: Eliminates ~400ms network latency per previously-searched domain. Prevents potential React/Svelte memory leaks during component unmount.
🔬 Measurement: Verified caching logic and timeout limits locally. Confirmed onDestroy cleans up debounce timers. Passed unit tests.

- Adds a module-level `Map` cache with a TTL (5 minutes) for search results in `DomainSearch.svelte`.
- Limits cache size to 500 entries with FIFO eviction to prevent SSR memory leaks.
- Normalizes search terms using `toLocaleLowerCase()`.
- Uses `onDestroy` to clean up the `debounceTimer` to prevent memory leaks and issues on component unmount.
