fix: expose steering input events

[zatevakhin]

Summary

• attach stable client input IDs to steer and queue requests
• print compact input lifecycle events from ACP notifications
• add discard-queued SESSION_ID INPUT_ID for pending queue removal

Why

CLI clients need stable correlation across accepted, queued, applied, started, and discarded input states, including explicit removal before execution.

📝 Walkthrough

Walkthrough

The CLI adds queued-input discard support and UUID-based input tracking. The client now streams normalized input-state events and writes session updates directly.

Changes

Queued input commands and identifiers

Layer / File(s)	Summary
Queued input commands and identifiers Cargo.toml, src/commands.rs, README.md	The CLI adds discard-queued, calls querymt/session/discardQueuedInput, and returns session and input identifiers. Submitted inputs now receive a v4 UUID and return clientInputId.

Input-state event normalization

Layer / File(s)	Summary
Input-state event normalization src/events.rs, src/client.rs	Input-state notifications are normalized into input_state events. The client writes these events when streaming is enabled and writes session updates directly within the streaming branch. Tests cover input-state and discarded-queue notifications.

Priority: ⬇️ Low

Estimated code review effort: 3 (Moderate) | ~20 minutes

Document the input-state event and identifier handoff.

prompt now emits input_state lifecycle events, but the NDJSON event list excludes them. The new discard-queued example also does not state whether INPUT_ID comes from clientInputId or lifecycle-event inputId. Document both parts of this contract so JSON consumers can correlate and discard queued input.
