Simplify CI: drop deploy workflow and per-service test matrices

[dantraynor]

Summary

• Delete .github/workflows/deploy.yml (GCP/GCE deploy is irrelevant for an example repo).
• Collapse ci.yml to two jobs: gitleaks and a single docker compose build that compiles every service.

Test Plan

• make doctor
• make test
• Dashboard checked, if UI changed

Safety Impact

• No execution behavior changed
• Dry-run behavior reviewed
• Kill-switch behavior reviewed
• Risk limits reviewed

Notes

CI no longer runs unit tests; the docker build proves compilation. Add a focused test job back if test signal is wanted. No operator action required.

Pull request overview

This PR simplifies GitHub Actions for the repo by removing the GCP/GCE deployment workflow and reducing CI to secret scanning plus a single Docker Compose build that compiles/builds all services as container images.

Changes:

• Removed .github/workflows/deploy.yml (no more automated image push + GCE deploy on main).
• Collapsed .github/workflows/ci.yml into two jobs: gitleaks and a single docker compose ... build.

.github/workflows/ci.yml:26

• This workflow no longer runs any unit/integration tests (previously cargo test and npm test per-service). docker compose ... build only proves images can build, and will miss failing tests/regressions that currently exist in the repo (e.g., Jest suites under strategy services). Consider adding a dedicated test job back (even a minimal make test, or cargo test for Rust + npm test for the key services) so CI still enforces behavior, not just compilation.

    runs-on: ubuntu-latest
    steps:

        run: docker compose -f docker-compose.yml -f docker-compose.dev.yml build

.github/workflows/ci.yml:26

• By removing the deploy workflow, the repo's operator/deployment docs become misleading (e.g., README mentions “GitHub Actions deployment” and docs/DEPLOY_RUNBOOK.md lists GitHub Actions secrets like GCE_INSTANCE_IP/GCP_SA_KEY). If this repo is now intended to be “example-only”, consider updating/removing those docs (or adding a short note pointing to manual deployment) so contributors don’t follow a CI/CD path that no longer exists.
