Add tests/_async/test_http2_goaway.py with 41 tests covering: - ConnectionGoingAway exception properties (is_safe_to_retry, is_graceful_shutdown, may_have_side_effects) - HTTP/2 connection GOAWAY handling and DRAINING state - Request phase tracking (headers_sent, body_sent) - Pool-level retry logic based on GOAWAY context Fix critical bug: reorder exception handlers so ConnectionGoingAway is caught before ConnectionNotAvailable (its parent class). The original order caused all GOAWAY exceptions to be caught by the wrong handler and retried unconditionally. Coverage achieved: - httpcore/_exceptions.py: 100% - httpcore/_async/connection_pool.py: 100% - httpcore/_async/http2.py: 97% https://claude.ai/code/session_01PbGidFEEpj8txq8Qt7refq
