Add joulehook-statusline: reads Claude Code's statusline JSON (the one place it
exposes its own token counts, SPEC §7) and shows an ESTIMATED joule figure —
Estimator provenance, labeled 'est', never passed off as measured — plus the
gate's sealed-decision count. INSTALL.md wires all three seams (gate hook + meter
statusline + receipt log) into one .claude/settings.json, and points at the Mesh
proxy for the authoritative/enforcing meter. 12 tests total; clippy-clean.
