- Replace fixed "5h"/"7d" window labels with hours/days remaining until
the rate-limit window resets, derived from rate_limits.*.resets_at.
- Wire up the previously-captured-but-unused $thinking variable as a
fallback marker when no explicit effort.level is present.
- Color-grade all three percentages (context, 5h, 7d): yellow >=80%,
red >=90%. Uses \e[39m to restore default fg without losing the
surrounding dim attribute.
