Job control + session reset for mobile/remote sessions

Preflight Checklist

• [x] I have searched existing requests and this feature hasn't been requested yet
• [x] This is a single feature request (not multiple features)

Problem Statement

When using Claude Code on mobile or a remote connection, a stuck tool call (e.g. a long-running grep) can make the session completely unresponsive with no way to recover short of abandoning the session entirely.

Proposed Solution

Job control — ability to cancel/kill an in-progress tool call (e.g. a "Stop" button next to "In progress" tool calls)

Session reset — a way to interrupt the current turn and return to a clean input prompt without losing session history, analogous to Ctrl+C in a terminal
