…flow Add skip guard to lean-proofs.yml: when no .lean source files exist in FVSquad/, all build steps (elan install, lake build) are skipped and the job completes successfully. This prevents spurious CI failures during the bootstrapping phase before any Lean files are committed. Also scaffold the FVSquad/ directory with a README documenting the planned targets and the skip-guard behaviour.

Pull request overview
This PR improves the Lean formal verification CI workflow robustness during bootstrapping by adding a guard that skips Lean build steps when no Lean source files exist yet in the FVSquad/ library, and scaffolds the FVSquad/ directory with initial documentation.
Changes:
- Add a “check for
.leanfiles” step and gate elan/cache/build steps behind it inlean-proofs.yml. - Update workflow comments to reflect the
FVSquad/-scoped Lean project intent. - Add
formal-verification/lean/FVSquad/README.mddescribing planned FV targets and the CI skip behavior.
