Per instruction to stop iterating on builds: reqwest 0.13's client-http
feature (needed only for an in-process MCP-client e2e test) was pulling
a very slow/heavy native build (aws-lc-rs, even with the TLS backend
stripped down) and the last attempt was still in progress -- unverified.
Reverting Cargo.toml to the last state that was actually confirmed
green (cargo fmt/clippy -D warnings/test, both default and --features
mcp, all passing) rather than ship an unverified dependency change.
The HTTP transport itself (bind_loopback/token gate/serve loop) keeps
its own unit tests, which did pass under --features mcp.
