sbx/claude-sbx-statusline-kit:20260813-b7d6aa30d2703bffb7c7a91d4e66e550f3f25285

Adds a two-line Docker Sandboxes status line to Claude Code (host, cwd, git branch, model, context %, memory, load, cost). Ships ~/.claude/statusline.sh and sets the statusLine key in ~/.claude/settings.json, merging so every other setting is preserved (an existing statusLine is intentionally replaced, since installing this status line is the point of the kit).
