Delete the deprecated Leaf derive path, migrate the remaining tests and example to leaf!, and add direct coverage for endpoint-only, TUI-only, and shared-host leaf declarations.
Introduce a function-like leaf declaration macro, bind endpoint and TUI hosts to shared generated metadata, and move remote shell endpoint construction out of the leaf module into the examples and runtime assembly code.
Update the remote shell examples to use unshell::leaves and the leaf_endpoint feature-gated endpoint module, and restore the local macro aliasing needed after removing the direct unshell dependency from unshell-leaves.
Move the protocol runtime into unshell-protocol and remote shell leaf code into unshell-leaves so endpoint and TUI roles can compile independently without circular dependencies.
Align the framed header section so decode can avoid hidden alignment repair on the hot path, and teach protocol_bench.rs to build and run the standalone tracing binaries directly. The updated benchmark shows lower encode, decode, forward, local call, and hook data costs than the previous baseline.
Make the standalone protocol operation examples return and print concrete checksums derived from protocol state so the traced work cannot be optimized away as dead computation.
Factor the benchmark scenarios into standalone example binaries that can be traced directly without cargo run, and simplify the hot call and hook lookup paths using the benchmark output as guidance.
Measure representative protocol paths in nanoseconds over hundreds of samples and report standard deviation so framing, routing, and local-delivery changes can be compared with less jitter.
