"""add chunks.start_char/end_char for citation offsets
Char offsets into the document's source_markdown (half-open span) let citations
resolve the exact passage a chunk came from. Nullable because historical rows
have no span; they populate on the next connector sync or user edit/reindex.
No backfill: a bulk UPDATE of every chunk on a large HNSW-indexed table rewrites
every secondary index per row (see migration 165 for the same reasoning).
Revision ID: 166
Revises: 165
