fix(ts-anthropic-cua): add try/finally to ensure browser session cleanup

Wrap replay stopping logic in try/finally to ensure browser session is
always deleted even if stopReplay() fails. This prevents resource leaks
on the Kernel platform when replay recording is enabled and stopping fails.

Matches the existing Python implementation behavior.
