A section that opens with a short header line ('דיון', 'טענות המשיבים')
followed by a paragraph larger than chunk_size flushed the header alone as a
tiny chunk. #55 added a query-time >=50 filter to hide these; this removes
them at the source.
_split_section: (1) don't flush a buffer still below MIN_CHUNK_CHARS — let it
absorb the next paragraph even if that overflows chunk_size, so a short header
rides with its following content; (2) fold a trailing tiny chunk back into its
predecessor.
Verified: re-chunked the 4 corpus docs that still had a tiny chunk
(ע"א 5138/04, בר"מ 2340/02, בג"ץ 6525/15, 403-17) — corpus-wide chunks<50
went 4 -> 0; all 4 stay embedded/searchable and rank top in a relevant search
(נווה שלום #1 for the s.19(ג)(1) exemption query). No regression.
