feat: include raw input in ACP permission requests

[ktwu01]

Related Issue

Fixes #734

Problem

ACP permission requests include the tool call summary and options, but the request did not carry the exact tool input. ACP clients that want to inspect the full command or payload had to parse display text or correlate an earlier tool-call update.

What changed

• Added rawInput to approval requests and populated it from the original tool-call args.
• Forwarded rawInput onto the ACP requestPermission.toolCall update.
• Added core, ACP, and SDK type coverage for the new field.
• Added a minor changeset for the affected packages.
