Coverage has grown well past the configured gates, so they no longer catch
regressions. Raise them to just under the measured values, per the standing
"regression ratchet, not a target" rule:
- frontend lines/statements 80 -> 95, functions 85 -> 89 (measured 96.52/91.08)
- frontend branches held at 85 (measured 86.78, the weakest metric)
- backend CI --cov-fail-under 50 -> 75 (measured 81)
Add NextSteps260914.md as the handoff for the next session. Delete todo.txt,
todo_260912.txt and todo-backend.txt, all fully done; NextSteps260913.md is
kept as history.
