5.7.7

(chore): Reduce verbose logging during OpenAPI parsing by moving individual example validation warnings to debug level. The per-API example validation summary is still shown at warn level.

(fix): Improve logging when APIs are skipped during docs generation. Skipped APIs now log at error level (instead of warn) with the API name and a clear reason. Repetitive per-endpoint frontmatter warnings are aggregated into a single summary line per API.
