Note

Low Risk
Lockfile-only transitive tooling update with security and bug fixes; minor risk that resolved browser targets in the build pipeline change slightly.

Overview
Updates yarn.lock to resolve browserslist from 4.21.3 to 4.28.8 (transitive build-time dependency; no direct package.json change in this diff).

The lockfile also refreshes related resolution entries: baseline-browser-mapping is added as a new transitive dependency, and caniuse-lite, electron-to-chromium, node-releases, update-browserslist-db, and escalade are bumped to versions required by the newer browserslist stack.

This pulls in upstream fixes and features across the 4.21→4.28 range (e.g. Baseline query support, ReDoS and prototype-pollution fixes, parsing/memory fixes, and assorted query regressions). Browser targeting for CSS/JS transpilation may shift slightly depending on existing Browserslist config.
