wip(proof-debt): rescue uncommitted #133 Coq/Lean CNO work [UNVERIFIED]

Swarm WIP for standards#133 (Lean CNO cons-case + Coq tier-0 rebuild)
was uncommitted in the shared clone with no branch. Only the 12 modified
proof source files are committed (build artifacts excluded); NOT
proof-checked yet — Phase-1 agent continues with coqc/lake as oracle.
Adds .lake gitignore guard.
