# Consensus Checker (TypeScript Wrapper)
# Collects and validates Loop 2 consensus scores
#
# Usage:
#   consensus-ts.sh --scores <score1,score2,...> \
#                   --threshold <0.0-1.0> \
#                   --mode <mvp|standard|enterprise>
#
# Returns:
#   Exit 0: Consensus reached
#   Exit 1: Consensus failed
