This PR addresses a code health issue where an empty test case existed in src/discovery/swim.zig.

🎯 What: The test case "swim creates sequential pings" has been implemented with functional logic and assertions.
💡 Why: Tests should contain assertions to verify behavior. This test now ensures that the SWIM protocol correctly increments sequence numbers and tracks pending pings.
Verification: The implementation uses an ephemeral UDP port (0) to avoid permission issues and includes thorough assertions. The code has been reviewed and follows established patterns in the codebase.
Result: Improved test coverage and maintainability by replacing a placeholder with a functional regression check.

- Implemented the 'swim creates sequential pings' test case which was previously empty.
- Added logic to bind a UDP socket to an ephemeral port to allow testing without root.
- Added assertions to verify sequence number incrementing and pending ping tracking.
- Ensured proper resource cleanup with defer.
