v0.24.0

Added

• PDF to text (src/io/pdf/content.rs, font.rs, text.rs): every page, or --page N, laid out as pdftotext lays it out; ToUnicode, the standard encodings with /Differences, Type0 Identity fonts, Type3, and the Core 14 widths (scripts/gen-pdf-tables.py). Matches pdftotext line for line on 14 fixtures, dehyphenation included.
• Benchmark pair pdf-text against pdftotext and the pdf-extract crate: every line passes (2.8x pdftotext on a 300-page report, 1.7x on 300 pages of base-14 text, under half its memory).
• PDF to Markdown, HTML, and Word (src/io/pdf/markdown.rs): headings from type size and weight (three levels by size and bold lines below them), bullet and numbered lists, paragraphs with hyphenated words joined, and page numbers dropped.

Performance

• Small one-shot inflates (a PDF page's content streams, small ZIP parts) start from a slab a few times their size instead of a megabyte, build the packed literal table only for inputs of 4 KB and up, and no longer build packed copies of the distance and code-length tables, which nothing reads: a 300-page PDF of 14,400 small streams reads its text in 0.13 s instead of 0.61.
