giles 83c9d60d72 scoreboard: 147/300 (49.0%) wide, up from 114/300 baseline
Math 40% / Number 73% / String 33% = 147/300 (49.0%), +33 tests since
session-3 start. Wall time 277s (vs prior 593s baseline → 2.14× via
harness cache).

Top remaining failure modes (141 fails, 12 timeouts):
- 115× Test262Error (assertion failed) — numeric precision at
  MAX_VALUE/MIN_VALUE boundary, (new Number()).constructor chain,
  toFixed edge cases, String.fromCharCode code-point ranges
- 34× TypeError: not a function — still the missing Math trig
  primitives (filed as Blocker)
- 12× Timeout — long-running String loops
