Macro program_dispatch 

macro_rules! program_dispatch {
    ($program_mod:ident) => { ... };
}

Generate the small runtime bridge for a #[program] module.

This keeps first-touch programs focused on #[program], Ctx<T>, and ctx.accounts.* while still emitting the audited Hopper entrypoint under the hood.

#[program]
mod counter_program {
    // handlers
}

hopper::program_dispatch!(counter_program);
