Stable merge / suppression key for an attachment. \`access\` is keyed per protocol (SNMP and SSH are distinct slots); \`metrics-binding\` is keyed per metrics source (two metrics sources can each bind one element — but ONE binding per (source, element) is the invariant; extend with a role segment if per-metric-role binding is ever needed, don't overload the slot); every other kind keys by its \`kind\`. The resolver merges attachments by this key (highest-priority contribution wins per key) and the human suppresses by it (\`suppressedAttachments\`). One definition so merge and suppression never disagree on what "the same attachment slot" means.
