📝 SummarySummary by CodeRabbit
WalkthroughTerminal closure now finalizes active shell processes, cancels pending shell-integration waits, clears terminal state, and prevents duplicate completion. The registry routes close events through this cleanup. Tests and a lifecycle model check cover closure interleavings. ChangesTerminal closure handling

real TerminalProcess.run() stream path: emit output, close the terminal before
onDidEndTerminalShellExecution, await the command result, and assert both
buffered output delivery and iterator cleanup. Keep the existing
direct-construction test unchanged unless needed, and place the regression at
the lowest valid harness with behavior-focused assertions.
- Line 350: Strengthen the assertions for completedSpy in both affected tests to
verify the callback payload, requiring an empty output string and the expected
process object rather than only checking call count. Keep the existing once-only
invocation requirement alongside these argument assertions.

What changed
pnpm lifecycle:model-check, alongside the task, store, provider-handoff/scheduler, cleanup-protocol, parser-scope, and completion-persistence models.Why this change was made
VS Code can omit both the shell execution end event and the OSC completion marker when a terminal is disposed. That left Zoo Code commands marked as Running indefinitely and blocked subsequent chat messages. Terminal closure must release every command and lifecycle resource associated with that terminal, not only the most recently attached process.
Closes #1362.
Impact
Closing a VS Code terminal now interrupts all startup-waiting and active Zoo Code commands tied to it, preserves buffered output, releases stream and shell-integration resources, clears running state, and prevents duplicate completion. Focused V8 coverage measures all 71 changed executable production lines (100% patch line coverage). The changed-code mutation gate kills all 93 generated mutants with no timeouts, survivors, or uncovered mutants; the full Zoo Code suite passes 8,303 tests with 39 skipped.
