Add bin/tracks-status.sh, a read-only bash+git script that reports repo location, the tracks.json declaration with defaults applied, base-branch existence, primary checkout cleanliness, and one block per worktree (branch, ahead/behind, clean/dirty, handoff presence, last commit time). track.md, tracks.md, and land.md now call it instead of describing a multi-command probe for a model to reinvent each run.
