feat: Add URL query parameter auto-load support
Enable loading user profiles via ?user= handle in the URL.
Changes:
- Add get_query_param() FFI function in effects.gleam
- Modify init() to check for user param and auto-fetch profile
- Add comprehensive tests for query param extraction and init behavior
- Clean up unused imports and dead test code
- Reorganize tests by module (effects_test.gleam)
All 92 tests passing.
