Bitbucket API Rules

# bitbucket — 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:
#   - path-params-casing: snake @ 99% (n=838)
#   - query-params-casing: snake @ 93% (n=100)
#   - operationid-casing: camel @ 100% (n=100)
#   - pagination params observed: ['page']
#   - merge: kept 19 existing, added 3 measured, upgraded 0
#   - added: query-params-casing, operationid-casing, no-empty-descriptions
