Function _get_section_bounds

openkb/agent/compiler.py:784–798

Return the [start, end) bounds for a Markdown H2 section. Uses ``_iter_h2_headings`` so the same H2 detection that finds the target heading also determines the section's end (the next H2). A drifted ``"## Documents "`` matches ``"## Documents"`` because both sides are normalized.
