Update the README, maintained documentation, contributor guidance, and hand-maintained mirrors to describe Agentic SAST, reconciliation, the Miscellaneous lane, current CLI behavior, and the final release contract. Correct stale workspace and container guidance and annotate long-standing internals for maintainers.
