fix(EC-24260): Update CI workflows

[yasinghasmi]

Summary

• Update all workflows to ubuntu-24.04, Node 24.x, and actions v4
• Replace publish-to-npm.yml with publish.yml using OIDC trusted publishers (no more NPM_TOKEN secret)
• Replace jest-tests.yml with build.yml that runs build + test on push to main and PRs
• Modernize prettier.yml (prettier_action v4.3)
• Modernize update-docs.yml and build-dist.yml
• Consistent naming and formatting across all workflows

Test plan

• Verify build.yml runs on a PR (build + test pass)
• Verify publish.yml works on next GitHub release (OIDC auth to npm)
• Verify build-dist.yml pushes to main-dist on merge to main
