Markdown Header Chunks
Split a Markdown document into chunks whose text length does not exceed maxChunkSize whenever possible. Lines must remain intact.
When a new chunk starts inside a Markdown header section, prepend the active header path to that chunk. For example, if the current content is under # A and ## B, the new chunk should start with those header lines before adding the next content lines.
Return each chunk as a display string where the lines inside that chunk are joined by | .
1Example 1
The second chunk repeats the active # A header before continuing content under that section.
2Example 2
The whole document fits within one chunk.
Constraints
Limits and guarantees your solution can rely on.
Header lines are lines whose first non-space character is #. If a single non-header line plus its active headers is longer than maxChunkSize, keep that line in its own chunk with the active headers.
