GHSA-72gw-mp4g-v24j / CVE-2026-5079 — DoS via deeply nested field names,
patched in 2.2.0. multer is a direct dep of web and clsi (file uploads).
- bump multer to 2.2.0 in services/web and services/clsi
- re-target the Overleaf local patch (attach files with no filename as
'undefined' instead of skipping) from 2.1.1 to 2.2.0, kept as a scoped
root resolution to match the repo's patch convention

* Add png to pdf converter for optimising image loading in pdftex
* refactor
* move fixtures
* refactor and add unit tests
* Remove gamma correction from PNG processing and update related tests
* Add crc32fast dependency and enhance PNG processing tests
* Add fixture test cases for PNG processing
* fix alpha channel to match pdftex
pdftex always uses an 8 bit alpha channel in the output even for 16 bit images
* Refactor PNG processing to use Option for alpha stream and update related logic
* Enhance PDF writing by adding DecodeParms for alpha stream and optimize PNG encoding process
* Add pixel dimensions support in PNG processing and PDF writing
* [copybara] move clsi excludes
* [clsi] move gitignore rules
* [png2pdf] move into dockerfiles folder
* [png2pdf] use atomic writes
* [clsi] integrate png2pdf
* [saas-e2e] add coverage for png2pdf
* [png2pdf] make compatible with seccomp profile in clsi
* [copybara] remove exclude following move of png2pdf
* [copybara] remove spurious excludes
* fix broken detection of malformed chunk headers

* [project-history] add build script flag for depending on doc-updater types
* [png2pdf] run tests as part of clsi pipeline
* [png2pdf] fix calculation of PDF page size
* [web] put png2pdf behind feature flag and make it opt-in
* [web] fix ClsiManager.promises.sendRequest invocation after merge
* extend is_copy_safe function to follow pdftex
see the conditions in pdftex's writepng.c
https://svn.tug.org:8369/texlive/trunk/Build/source/texk/web2c/pdftexdir/writepng.c?revision=78081&view=markup#l575
the criteria are not an exact match because the png crate does not support all the
png chunk types
https://github.com/image-rs/image-png/issues/116
if the criteria result in a png being converted or skipped the final result should be the same.
in one case the conversion will be done by pdftex (at runtime)
in the other case the conversion will be done by png2pdf -
both conversions should give the same result.
* include tests in png2pdf Dockerfile
* [clsi] explicitly disable png2pdf conversion for project conversion
* [clsi] png2pdf: count converted files
* [png2pdf] bump date in docker image tag
* [web] make draft-setting option wider when png2pdf is available

This was useful when iterating on the pdf-caching feature.
PDF caching has been stable for years. We can remove the logging now.
