# Pre-tag tripwire for beta releases. Refuses to allow tag operations when
# .claude-plugin/plugin.json `version` does NOT end with `-beta.N` and when
# package.json drifts from plugin.json. Pure file-state check; never invokes
# git. Runs BEFORE Task 6a's release commit and BEFORE Task 6b's tag in the
# Phase 89.6 release-gate plan.
#
# Reference: .planning/phases/89.6-release-gate-beta-1/89.6-CONTEXT.md (Area 4
# Q1 — tripwire decision); .claude/includes/release-process.md (§Version
# Consistency Rule + §Pre-release versions for beta testing).
#
# Exit codes:
#   0 — plugin.json version matches `-beta.N` AND package.json agrees
#   1 — version does not match, files disagree, or files missing
