…ned" markdownChunker recurses one header level at a time and prepends each section's header to every chunk it produces. When a section has no header, findHeader returns undefined and the template literal interpolated it as the literal text "undefined", so headerless docs were indexed with up to five bogus "undefined" lines at the top of every chunk. Only prepend the header when the section actually has one.

markdownChunker prepends each section header to every chunk. When a section has no header, findHeader returns undefined and the template literal interpolated it as the literal text "undefined". Headerless docs were indexed with up to five bogus undefined lines at the top of every chunk (used by @docs indexing).
Only prepend the header when the section actually has one.
Tests: cd core && npx vitest run indexing/chunk/markdown.vitest.ts — 3 passed. Distinct from #13140-#13148.
