docs: update wiki
docs: repoint remaining reorganization paths (blob URLs, deploy, scanners, kb, internal) Absolute github blob/tree URLs and inline path references that still pointed at the pre-6.9 top-level layout: readmes/ -> docs/readmes/, deploy/single-host -> tooling/deploy/single-host, guinea_pigs -> testing/guinea_pigs, knowledge_base -> services/knowledge_base, the scanner dirs -> scanners/<name>, and internal/ + validation-benchmarks -> _local/.
