Fix cancelled install temp-directory cleanup (audit-resource-lifecycle-audit-002)

[kitsuyui]

Fix implemented

• Added parent-side temporary workspace cleanup in install-app-async-core so cancellation now removes temporary directories deterministically.
• Passed tmpPath to install-app-forked-lite so the child uses the same workspace while retaining its existing cleanup fallback.
• Maintained existing install success/error IPC semantics and finalization flow.

Verification

• Not run in this implementation step: no test execution requested.

Closes: audit-resource-lifecycle-audit-002
