* [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

* [k8s] clsi-cache: migrate to StatefulSet
* clsi-cache: optimize ILB services for GKE subsetting
Update the new clsi-cache internal load balancer services
to use optimal settings for GKE subsetting (NEG backends):
- set allocateLoadBalancerNodePorts: false (not needed with NEGs)
- set externalTrafficPolicy: Local (preserve source IP, keep traffic in zone)
- add trafficDistribution: PreferClose (zone affinity)
These settings ensure traffic from CLSI VMs stays within the same zone
when possible, reducing latency and cross-zone network costs.
* [k8s] clsi-cache: add missing resource paths
* [clsi] exclude readOnly clsi-cache shards
