v202604240140longchunk still hit 400 Bad Request from nomic-embed-text
on several batches — the chars/4 token estimate was optimistic for
code-heavy/Unicode content. Rebuilt from FlowerCore.Common@e1c28b4
which tightens MarkdownChunker hard cap (ChunkSizeTokens × 2, clamped
at 16000 chars) AND adds a character-length check in IndexBuilder's
safety filter alongside the estimated-tokens check.
