fix: detect permission prompts as NeedsInput when tool_use is stale (>10s)

When Claude requests a tool permission approval, the last JSONL entry is
type=assistant with stop_reason=tool_use. Previously this was always
classified as Working. Now, if the tool_use entry is older than 10s with
no new activity, it's classified as NeedsInput.

Also fix vmux label to accept fuzzy match queries (not just session UUIDs).
