What changes have been made

RHOAIENG-61475: ai scaffolding tier1

Added ruff linter and formatter to the codeflare-sdk project with configuration in pyproject.toml,
pre-commit hooks, and a new CI workflow (.github/workflows/lint.yml) that enforces code quality on every commit and PR. 
Import sorting was intentionally disabled to avoid circular import issues, while pyflakes and pycodestyle rules were enabled with pragmatic ignores for existing codebase patterns, auto-fixing 71 lint errors and reformatting 32 files.

Verification steps

Sanity check the changes - they conform to the specification from here (tier 1 only for now)

the changes were verified by running pre-commit with new checks and then by running e2e tests from an image built from this branch against an OpenShift cluster with RHOAI 3.4 installed

Checks

• I've made sure the tests are passing.
• Testing Strategy
  • Unit tests
  • Manual tests (e2e on Openshift)
  • Testing is not required for this change
