benchkeeper 6.23

• App, benchkeeper insights --json (#321, part of #273): findings with a stable id, a severity, the evidence and a fix from three signals. Installed Claude Code skills (global folders and enabled plugins) that none of the sessions of the last 90 days used, with the tokens their descriptions cost per turn: it needs 20 sessions in that window and reports nothing below that. The doctor's findings, as hygiene. Pins behind the newest release, as freshness: the doctor's pins and outdated items and the skills of registered projects behind the library. --project dir adds that project's doctor checks. Insights is a view of its own in the UI, which comes in a later child; the text form of the command does too. The keys are in the table of machine-readable documents in app/README.md.
• Plugin version 6.23.0.
