Shared between /ship (legacy path) and the CI version-gate job. detect-bump: derive bump level from VERSION diff. compare-pr-version: CI gate logic with three exit paths (pass / block / fail-open). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

// detect-bump — crude heuristic for picking a bump level from a VERSION pair.
|
|
// Used by CI's version-gate job to re-run the util with the "same" level that
|
|
// /ship used, without needing persisted bump-intent.
|
|
//
|
|
// Input: two VERSION strings via argv: current (base) and target (branch).
|
|
// Output: a single word: major|minor|patch|micro
|
|
//
|
|
// Heuristic: compare slot-by-slot. The first slot that differs IS the level.
|
|
// If nothing differs (shouldn't happen when called by CI gate — the whole point
|
|
// is the branch bumped VERSION), default to "patch".
