Specifies pre-building tessellation JARs into a Docker image to reduce E2E CI time from ~16 min to ~10 min (~40% improvement). Key decisions: - Only tessellation JARs pre-built (gl0/gl1/keytool/wallet) - Metagraph JARs (ml0/cl1/dl1) still built from source every PR - SKIP_ASSEMBLY=true + PUBLISH=false in e2e.yml - JAR-only scratch image, extracted via docker create + docker cp - Public image (no auth required for pulls) - Manual dispatch + auto-rebuild on patch changes Phase 2 (sbt incremental cache) deferred to separate card. Resolves: Pre-build tessellation/ottochain Docker images (Trello #69967833)

Implements spec from PR #101. Reduces E2E CI time from ~16 min to ~8-10 min by pre-building tessellation GL0/GL1 JARs and using SKIP_ASSEMBLY=true. Changes: - New .github/workflows/build-tessellation-base.yml Builds tessellation assembly JARs and publishes to ghcr.io/ottobot-ai/tessellation-base:v{VERSION}. Triggers on push to paths: build.sbt, project/**, patches/, Dockerfile. Also supports manual dispatch. - New tessellation-base.Dockerfile Minimal alpine image containing only GL0/GL1 assembly JARs. ML0/CL1/DL1 (OttoChain) intentionally excluded — built per-PR from source. - Updated .github/workflows/e2e.yml Pulls pre-built base image, extracts JARs via docker create+cp to tessellation target directories, then runs just up with SKIP_ASSEMBLY=true PUBLISH=false. - Added modules/ci with TDD tests (43 tests from PR #102). File-content tests now pass (workflow/Dockerfile structure verified). Runtime tests (CI timing, actual image pull) remain in TDD red phase until image is built and pushed to GHCR.
