Root cause: upstream_request_filter was inserting x-forwarded-proto with a raw headers.insert() call (via DerefMut) which only updates base.headers but NOT the CaseMap. header_to_h1_wire zips CaseMap with base.headers, so headers added without a CaseMap entry are silently dropped on the wire. Fix: use insert_header() which keeps both maps in sync. Also adds: - src/lib.rs + [lib] section: exposes SunbeamProxy/RouteConfig/AcmeRoutes to integration tests without re-declaring modules in main.rs - tests/e2e.rs: real end-to-end test — starts a SunbeamProxy over plain HTTP, routes it to a TCP echo backend, and asserts x-forwarded-proto: http is present in the upstream request headers - Updated unit tests to verify header_to_h1_wire round-trip (not just that HeaderMap::insert works in isolation) Signed-off-by: Sienna Meridian Satterwhite <sienna@sunbeam.pt>
