refactor(lee): drop the loader guest binary, native-only Deploy

Deploy is not intended to ever run privately, and public dispatch
already always takes the native fast-path for it, so the guest ELF
had no real execution path left. Removes lez/programs/loader's guest
binary crate, its [[bin]] wiring, programs::loader(), and the
now-pointless guest-vs-native equivalence test along with the
test-only Program::execute_for_test it depended on.

loader_core (Instruction, ProgramData, execute_deploy) stays — native
dispatch still calls it directly. Deploy is now honestly just native
dispatch logic with a program-shaped interface, not a program with a
guest binary nobody executes.
