Sys1 v0.15.0

Sys1 adds Devin setup for agent review and a read-only sys1 usage report on how often coding agents use Sys1, and adopts a new one-line description.

Changes

• sys1 review setup devin installs the project review skill at .devin/skills/sys1-review/SKILL.md, alongside the Codex and Claude Code targets. It adds no hooks and configures no models.
• sys1 usage [--days <n>] counts sys1 subcommands, system-one-skills check runs, and Sys1 or System One skill loads in local Devin, Claude Code, and Codex transcripts, per agent and per day. It prints counts only, never prompt text, command text, paths, or source, and makes no model calls.
• The one-line description now reads: Sys1 helps coding agents review changes against your repository's rules, with probability-scored answers from hosted Jev, a local model, or your own server. Review remains experimental and advisory.
