collectMergeKeyDiagnostics
function collectMergeKeyDiagnostics(ctx): Diagnostic[];Defined in: packages/core/src/strict.ts:38
Flag YAML 1.1 merge keys (<<) in .actio.yml source for repos enforcing a
strict YAML 1.2.2 style. Lint-only: Actio still resolves and erases << at
parse, so emitted YAML is byte-identical whether or not strict mode is on.
Anchors and aliases (&/*) are valid 1.2.2 core and are never flagged.
