- Line 305: Extend the TerminalRegistry regression coverage by exercising the
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.

In `@src/integrations/terminal/__tests__/TerminalRegistry.spec.ts`:
- Around line 545-550: Update the test around runCommand to capture the expected
process from terminal.process and assert completionSpy and completedSpy receive
that exact reference with toBe, rather than deriving it from
completedSpy.mock.calls. Avoid indexing spy calls so a missing onCompleted
invocation produces a clear assertion failure.
- Line 615: In the relevant describe block of TerminalRegistry.spec.ts, add an
afterEach hook that calls vi.useRealTimers() to guarantee timer cleanup after
every test, including failures. Remove the trailing vi.useRealTimers() calls
from the three tests that individually enable fake timers, while preserving
their existing vi.useFakeTimers() setup.

What changed
pnpm lifecycle:model, composed with the task, store, cleanup-protocol, parser-scope, and completion-persistence models throughpnpm lifecycle:model-check.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.
Closes #1362.
Impact
Closing a VS Code terminal now interrupts its active Zoo Code command, preserves buffered output, releases stream resources, clears running state, and allows the task to continue without duplicate completion. Focused V8 coverage measures all 44 changed executable production lines (100% patch line coverage). The changed-code mutation gate kills all 64 generated mutants with no timeouts, survivors, or uncovered mutants; the full Zoo Code suite passes.
