Summary

shield the pooled live snapshot from individual caller cancellation
give the shared snapshot task one bounded deadline for every attached waiter
cancel and await active snapshot work before closing the Gitea transport

TDD proof

RED: disconnect test failed because _live_snapshot_task became None
RED: shared deadline test failed because upstream work remained active
RED: shutdown test observed stop (active) before snapshot cancellation
GREEN: pytest -q → 118 passed in 2.38s
python3 -m compileall -q src tests
git diff --check

Closes #137
