content negotiation. Includes: - SSZ and JSON encoding/decoding for relay get_header responses - Content-Type and Eth-Consensus-Version header parsing - Accept header forwarding to relays with q-value ordering - MIME parameter tolerance on relay response Content-Type - Fork-aware SSZ bid value extraction for all supported forks - Mock relay and validator SSZ support in test infrastructure - get_header integration tests for both encodings - Dynamic port allocation in tests via get_free_listener

Summary
Rewrites get_header relay communication to support both SSZ and JSON content negotiation.
What's in this PR
get_free_listener(eliminates flaky CI from port collisions)Review notes
The route handler always takes the standard validation path in this PR. Configurable validation modes come in PR 4.
The test infrastructure changes (mock relay SSZ support, dynamic ports) are shared by both get_header and submit_block tests.
Part 2 of 4: SSZ types → get_header → submit_block → validation bypassing
Attribution
This work builds on the SSZ builder flow originally implemented by @eserilev
in #252 and ported to the current codebase by @jclapis in #403.
