TypedArray setters clarified; ESMeta tooling refreshed

A small week focused on editorial TypedArray return-value cleanup and a workflow/tooling bump for ESMeta checks.

TypedArray setter return values clarified

The spec now makes the setter-style operations explicit: SetViewValue is treated as returning unused, while the typed-array and DataView setters perform the write and then explicitly return undefined. This is an editorial consistency pass that better matches the intended behavior of these APIs.

ESMeta toolchain bumped in repo checks

The repo’s validation workflow was updated to use ESMeta installer v0.8.1, with corresponding esmeta-ignore.json adjustments to match the newer analyzer output.

Other misc changes
