feat(workout): hide registry conversion from golden path

Let the Workout generated interaction builder satisfy DispatchRegistry directly and guard canonical sources/docs against .into_registry() so the beginner path does not teach manual registry conversion.

 - Avoid project trees, architecture maps, generated inventories, current file sizes, issue lists, TODO inventories, and other snapshots that will rot.
 - Stable commands: `cargo run -p hemx-xtask -- test`, `cargo check --workspace`, `redgate health --strict`. Use the xtask runner for full verification so jobs are capped from local CPU and memory. req: test/004
 - Run the workout product exemplar with `cargo run -p hemx-xtask -- workout dev` and open `http://127.0.0.1:3028`; set `HEMX_WORKOUT_ADDR=127.0.0.1:3030` if the default port is busy. Its durable visual direction and recovery expectations live in `examples/workout/DESIGN.md`. req: examples/001

 - hemx core stays small: effects, typed ids, registries, and wire schema only.
 - Routing, auth, sessions, transport, transitions, sync, and storage belong in integration/user crates.
 - Public examples and beginner APIs should use generated resources and `IntoEffect`, not raw ids or runtime opcodes.
