Limits of the code extractor

What tree-sitter extraction covers

languages36Pinned by a unit test.
file size2 MiBPer source file. A larger file is refused, and the refusal names the cap.
symbols5,000Per file. The array stops at 5,000.
name length200 bytesA longer symbol name is skipped.
Caps from extract/code.rs. A file that a grammar fails to parse is indexed as plain text, not dropped.
