feat: add attestations package to quartz experimental
Implement the Attestations NIP with four event types:
- AttestationEvent (31871, addressable) - validity claims about other events
- AttestationRequestEvent (31872, addressable) - request attestation from attestors
- AttestorRecommendationEvent (31873, addressable) - recommend attestors for kinds
- AttestorProficiencyEvent (11871, replaceable) - declare verification proficiency
Each event follows Quartz's tag-per-file pattern with TagArrayExt and
TagArrayBuilderExt for reading/building tags.
