docs: bring the unreleased changelog entries to the released style

[titouanmathis]

Every entry under a released heading is one line ending in its pull request:

- Add `npm run measure` reporting the module graph of every published entry point … ([#757](https://github.com/studiometa/js-toolkit/pull/757))

Every entry under [Unreleased] was a paragraph with no reference. After #833 landed a short linked entry, the section read two ways at once.

All eight now match. The detail they carried is in the pull requests — #777 for the build and toolchain moves, #830 for the benchmark migration — which is where a reader who wants the mechanism looks anyway, and where it stays correct as the code moves.

One line was dropped rather than shortened: the note that Vitest 5 is blocked on bench() becoming context.bench. That is a plan, not a change, and a changelog is the wrong place for it. It is in #777 if anyone needs it.

Nothing but CHANGELOG.md is touched.

Code Review

Risk: Low — The changelog-only formatting update is safe to merge.

Rewrites the eight unreleased entries as concise, one-line entries with pull-request references, while preserving their substantive change descriptions. It also removes the Vitest 5 planning note as described in the intent.

Code Review

Risk: Low — This documentation-only change is safe to merge; no blocking issues were found.

Updates the eight unreleased changelog entries to the one-line format used by released entries and adds pull-request references for each. It also removes the Vitest 5 planning note, consistent with the stated intent that changelogs document changes rather than future plans.
