ProjectVD

Review Lean 4 / Mathlib files the way maintainer Jireh Loreaux (`j-loreaux`) would — checking naming conventions, proof style and tactics, attributes, formatting, docstrings, and API/design against patterns learned from 324 of his review comments on Stefan Kebekus's mathlib PRs. Auto-fixes mechanical issues, verifies tactic rewrites with `lake build`, and flags judgment calls in his voice. Use before submitting a mathlib PR, when cleaning up Lean files, or when the user runs /autoJireh.
