v3.12.0

📣 New: splitrail web, a local usage dashboard. Run splitrail web and open http://127.0.0.1:8765 to see your usage in the browser. It has an overview with cost, token and cache trends, rankings by model, tool and project, and an activity heatmap. A Sessions view lets you search, sort and see per-session detail, and a Breakdown table exports to CSV. Worktrees of the same repo roll up into one project. It's read-only and local-only (bound to 127.0.0.1), and the last scan is cached so it opens instantly. Available in English, Simplified Chinese and Traditional Chinese, with dark mode and phone layouts. Thank you @jimyag!
