Spec wording cleanup across numeric algorithms
A broad editorial pass rewrote several algorithm branches to use explicit step-by-step returns instead of inline "otherwise" phrasing. This makes control flow easier to follow and keeps numeric operations like exponentiation, multiplication, division, and comparisons more consistent, without changing behavior.
Realm initialization now names intrinsics unambiguously
The realm initialization text now points directly to the table's "Intrinsic Name" column when populating intrinsic field names, removing ambiguity for implementers reading the spec.
Other misc changes
- Minor wording cleanup in typed array conversion terminology
