User Story

As a developer
I want the CI pipeline to use pre-built base images and run steps in parallel
So that pipeline duration is significantly reduced and I get feedback faster

Context

Current CI pipeline installs the full Ruby toolchain from scratch on every run. Both lint and test steps pull ruby:3.4.9-slim, then run apt-get update, install build packages, gem install bundler, and bundle install. This happens twice sequentially, plus a third bundle install in the Kaniko build step. The platform already maintains a ruby-rails-build image in Harbor (ldraney/base-images) with Ruby, bundler, build tools, and native headers pre-installed. Using it eliminates the redundant package installation. Additionally, lint and test have no data dependency on each other but run sequentially by default — adding depends_on: [clone] makes them parallel.

File Targets

Files the agent should modify:

.woodpecker.yaml — change step images, remove apt-get/gem install, add depends_on, add BUNDLE env overrides

Files the agent should NOT touch:

Dockerfile — production build is separate from CI steps
Gemfile / Gemfile.lock — no gem changes needed

Acceptance Criteria

Lint and test steps use harbor.harbor.svc.cluster.local/library/ruby-rails-build:latest
No apt-get or gem install bundler commands in lint or test steps
Lint and test run in parallel via depends_on: [clone]
BUNDLE_DEPLOYMENT and BUNDLE_WITHOUT overridden to empty strings for CI
Pipeline completes successfully

Test Expectations

Push to branch triggers pipeline with new config
Lint step passes with base image
Test step passes with base image and Postgres service container
Run command: push to branch and verify in Woodpecker UI

Constraints

Must use internal Harbor URL (harbor.harbor.svc.cluster.local) not external (harbor.tail5b443a.ts.net) for in-cluster pulls
Base image sets BUNDLE_DEPLOYMENT=1 and BUNDLE_WITHOUT=development — CI needs both overridden to empty
library Harbor project must be accessible to Woodpecker agent (should be public)
