[core] Poison brace-depth tracking once it goes negative

Address Copilot review: the prior comment promised that a negative depth would never re-enable splitting, but an arithmetically-balanced later { could bring depth back to 0 and resume flushing mid-stream. Track an explicit 'poisoned' flag set once depth < 0 that permanently disables further flushes for the rest of the input. Adds a regression test where a leading } and a later { would have re-enabled splitting without the poison flag.
