fix(harness): gate kickoff/lock entry works in RPC mode (not only interactive)

- Removed event.source === "interactive" guard from entry detection so
  /nuova-domanda and /riprendi-sessione activate lockActive+pendingKickoff
  regardless of source (TUI or RPC prompt).
- Removed event.source !== "interactive" from free-input filter; lock now
  blocks/steers all user input when active, not only interactive keystrokes.
- Added typebox@1.1.38 devDep + fake_pi_runtime.registerCommand (gap from Task 2).
- New test: gate_entry.test.js (2 tests: lock activates on RPC; !-steer passes).
- Full suite: 19/19 pass, zero regressions.
