Apache HTTP Server API Rules

# apache-httpd — 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:
#   - operationid-casing: camel @ 100% (n=4)
#   - schema-names-casing: pascal @ 100% (n=4)
#   - schema-properties-casing: pascal @ 39% (n=28)
#   - merge: kept 7 existing, added 4 measured, upgraded 0
#   - added: operationid-casing, schema-names-casing, schema-properties-casing, no-empty-descriptions
