feat(cli): add mid-execution interrupt to allow hints/file-locations while model runs

What feature would you like to see?

Let users send hints or file paths to the running model without stopping it. The CLI forwards the input non-blockingly and the model incorporates it if relevant.

Example:

While CLI prints Searching repository..., user types hint: src/helpers/io.js → CLI forwards the hint and the model updates its search.

Acceptance criteria:

• CLI accepts non-blocking input while model runs.
• Model integrates or queues hints and reports what was applied.
• CLI shows acknowledgement (accepted/rejected/queued).
