Pull request overview

This PR addresses #7590 by adding a CI guardrail that verifies the committed docs/parameters.yaml matches the parameter metadata embedded in the C++ source, preventing the docs from drifting when INPUT parameters change.

Changes:

• Adds a GitHub Actions step that runs abacus_* --generate-parameters-yaml and diffs the output against docs/parameters.yaml.
• Emits a clear failure message with regeneration instructions and prints a diff on mismatch.
