Resuming a truncated thinking block now also checks it won't overflow the context limit

What

The still-off-by-default feature that lets Claude Code resume a thinking block that was cut short now adds a check before resuming: if resuming would push token usage over the context limit, it skips the resumption instead, logging the reason as skipped_context_limit.

Why

This prevents resuming a truncated thinking block from causing the conversation to exceed its context window, avoiding a failure mode where continuing the thought would break the session.
