Documentation versioning

WebProbe documentation is immutable by major API version. The current material is published under /v1/, and its machine-readable contract is available at /v1/openapi.json. The unversioned root redirects to the current supported version.

docs/versions.json is the release manifest. Its release value displays the exact product release while id and label identify the stable API compatibility line. A new major version receives a new source snapshot and output directory; existing version sources remain available for clients that have not migrated. The version selector preserves the current page when the same guide exists in another version.

Patch releases update the matching major-version documentation and OpenAPI info.version. Breaking request or response changes require a new major documentation version.
