doc_reduce, the engine's reduced_bytes doc, the optimize README's
presets and the optimize.reduce parity note still said every image
above 225 ppi goes to 150 ppi; black-and-white images go to 300 ppi
above 450 ppi, as CCITT Group 4 when smaller.

- Redaction doesn't decode CCITT, so a mark over part of an image the
optimizer stored as Group 4 removes the whole image (nothing leaks),
and Export ▸ Images refuses it. The optimize README and the
mono-compression parity note say so. Later PRs of this stack add both
(#4335 export, #4384 redaction).
- doc_reduce's description, Engine::reduced_bytes and docs/cli-batch.md
now list the black-and-white step; docs/target-app-parity.md's
optimize row gives the measured counts and no longer lists CCITT as
missing; the M11 milestone row lists it as done.
From reviews with the pdfcraft-review skill.
