Debian 11 (bullseye) LTS ended in August 2026 and its security packages are no longer served from deb.debian.org, so apt-get install in the CLN builder stage fails with 404s and the cln image in the dev docker-compose cannot be built. The builder only compiles the holdinvoice plugin, which is copied into elementsproject/lightningd:v25.09.3. That image is already based on bookworm (glibc 2.36), so building on bookworm also matches the runtime. CLN and holdinvoice versions are unchanged.

Fixes #2827
Moves the CLN builder stage in
docker/cln/Dockerfilefromdebian:bullseye-slim(end of life; its security packages now 404) todebian:bookworm-slim. That matches the Debian release of the finalelementsproject/lightningd:v25.09.3image. CLN (v25.09.3) and holdinvoice (v4.0.0) versions are unchanged.Tested on Apple Silicon: the
clnimage builds, and the holdinvoice plugin compiles and is copied into the final image. I haven't exercised hold invoices against this build.Checklist before merging
