Standardize CI/CD pipelines

[andersondario-er]

Summary

Split monolithic main.yml into separate develop.yml and release.yml, standardize image tags. Public repo — uses internal reusable workflows (not serca-pipelines).

Changes

• Split main.yml into:
  • develop.yml — triggers on develop, builds + deploys to er-dev
  • release.yml — triggers on release-*, builds + ST build + deploys stage → approval → prod-me
• Image tag: Changed from branch-run_number to branch-short_sha
• Job names: Standardized (deploy-dev, deploy-stage, deploy-prod-me, approve-prod, etc.)
• ST build: Kept in release.yml (still needed for legacy single-tenant)

Standard Applied

Convention	Value
Dev workflow	develop.yml
Release workflow	release.yml
Image tag	{branch}-{short-sha}
Approval gate	production-approval environment
Primary registry	serca-artifact-registry/earthranger
