Amnic API Rules

# amnic — Spectral ruleset (strengthened)
# Plain Spectral. Existing hand-authored rules preserved; measured rules added
# from this provider's own OpenAPI conventions by strengthen_ruleset.py,
# then self-validated against the spec.
#
# Provenance:
#   - servers-https-only: 100% of servers already https (error)
#   - servers-expected-domain: 1/1 servers on amnic.com
#   - schema-names-casing: pascal @ 100% (n=5)
#   - security: global (root) — NOT emitting operation-security-required
#   - error-schema-defined: ErrorResponse
#   - merge: kept 31 existing, added 3 measured, upgraded 0
#   - added: servers-expected-domain, schema-names-casing, error-schema-defined
