add pinocchio cross-program-invocation example (#584)

Ports the hand+lever CPI example from anchor/native to Pinocchio.

- Two-program workspace: hand (caller) and lever (callee).
- Lever exposes initialize and switch_power instructions via a 1-byte
  discriminator; uses pinocchio-system::CreateAccount for account
  allocation under its own program id.
- Hand forwards switch_power(name) over CPI to lever, building the
  cross-program Instruction on the stack (no_std, no allocator).
- Bankrun TS test exercises the full init -> pull -> pull-again flow
  plus an invalid-discriminator rejection case.
