Fixes #63427

Adds Math.sumPrecise type definition for the ES2026 Math.sumPrecise API (TC39 proposal-math-sum, Stage 4).

Changes

  • Created src/lib/esnext.math.d.ts with the Math.sumPrecise declaration
  • Added /// <reference lib="esnext.math" /> to src/lib/esnext.d.ts

Note

Additional build system changes (libs.json, commandLineParser.ts, utilities.ts) may be needed for proper integration. Feedback welcome on whether these are required.
