🧹 Remove unused Talk component

[Sparkier]

🎯 What: The unused src/lib/components/cv/Talk.svelte component file was deleted.
💡 Why: The component was no longer being imported or used anywhere in the src directory. Deleting dead code improves code health, readability, and overall maintainability.
✅ Verification: Ran bun run lint, bun run check, bun run build, and bun run vitest to confirm that the project still builds properly and that all tests still pass, ensuring no existing code depended on the removed file.
✨ Result: The codebase is cleaner and no functionality was altered.
