Deliverect API Rules

# deliverect — 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: 20/20 servers on deliverect.com
#   - path-params-casing: camel @ 99% (n=82)
#   - query-params-casing: snake @ 69% (n=16)
#   - operationid-casing: snake @ 95% (n=104)
#   - security: global (root) — NOT emitting operation-security-required
#   - pagination params observed: ['page', 'size']
#   - merge: kept 32 existing, added 4 measured, upgraded 0
#   - added: path-params-casing, query-params-casing, operationid-casing, no-empty-descriptions
