Problem: parse_buffer classified /id/-prefixed task lines as headers because '/' matches the '^%S' header pattern. Store timestamp test was flaky when add and update ran within the same second. Solution: check for task line patterns (id prefix or 2-space indent) before falling through to the header branch. Backdate the initial modified timestamp in the store update test.
