Subject: [PATCH] fix(fuzz): link http_protocol_handlers.c + grpc.c into
 embedded harnesses
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

fuzz_http1_parser / fuzz_h2_session failed at link time — http_parser.c's
on_headers_complete calls http_request_classify_protocols and
http_request_body_must_buffer (src/core/http_protocol_handlers.c), which
in turn calls grpc_request_mode (src/grpc/grpc.c). Neither TU was in the
harness source list, so the CI 'Fuzz embedded' job was red at link.

Both TUs are self-contained (PHP-core symbols only, no server-side deps),
so add them to HTTP1_SRC and H2_SRC rather than stubbing — the fuzzer now
exercises real gRPC classification. Verified: both harnesses build and
link; fuzz_http1_parser runs 50 iterations clean (cov 91->255, no crash).
