onData creates+sets a pty record before the stopped-state guard, and onExit deletes the record instead of leaving a tombstone. A data chunk arriving after onExit (the exit-then-data race in pty.ts shutdown) resurrected a fresh record that nothing ever deleted, and double-counted the session. ptyId is a fresh per-spawn UUID, so the three ptyId-keyed maps grew unbounded. Track exited ids in a bounded FIFO and refuse onData resurrection for them. Regression test fails before the fix (record resurrected, 200 leaked) and passes after.
