Editorial TypedArray cleanup and toolchain refresh

September focused on spec-editorial TypedArray cleanup plus ESMeta/ecmarkup maintenance; no behavioral changes.

TypedArray spec text was tightened up

Several editorial updates clarified how typed arrays interact with indexed elements and setters. The spec now uses TypedArrayGetElement/TypedArraySetElement in more places, makes setter flows explicitly return undefined, and cleans up related abstract operation wording for consistency.

Naming and wording polish across the spec

A small editorial sweep improved internal variable and identifier naming for readability, along with minor wording fixes like standardizing “time zone” terminology.

Repo tooling was refreshed

The month also included a lightweight maintenance update to the spec build/check toolchain: ecmarkup was bumped for searchable output, and ESMeta was upgraded with matching ignore-list adjustments.

Other misc changes

  • Lockfiles and workflow metadata were updated to match dependency/tooling bumps.
