* [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

* using CLSI logic for fetching the project contents and skip the .zip export
* Use unique conversion directory for project-to-docx export to avoid corrupting the shared compile
directory when a compile runs concurrently
* Remove X-Accel-Buffering header — not needed as CLSI does not run behind nginx
* moving log before sending the data
* Return CLSI stream directly instead of buffering to disk on web
Previously convertProjectToDocx wrote the CLSI response to a temp file
on disk, then the controller read it back to stream to the client.
Now the stream is returned directly and piped to the response,
avoiding unnecessary disk I/O on the web server.
