[chore] Upgrade repository to Yarn 4 with Mise (#3406)

sjchmiela · web-flow · commit 37165428d120 · 2026-02-18T09:50:28.000+01:00
## Why
- Repository maintenance: standardize on Yarn 4 managed via Mise.
- Prepare for introducing minimum package-age constraints in dependency policy.

## How
- Migrated repo tooling to Yarn 4 with Mise.
- Updated CI and scripts for Yarn 4 behavior:
  - Lerna invoked via `yarn run -T lerna`.
  - Coverage args forwarded correctly (`-- --coverage`).
  - Removed unsupported Yarn 4 `--silent` usage.
- Added missing package-local script dependencies surfaced by Yarn 4 (`jest`, `oxlint`, `rimraf`).
- Increased `EasCommand` coverage test timeout from 30s to 60s. (Was consistently failing in CI.)

## Test Plan
- CI only: `Run tests` matrix (including Node 20 coverage) and other touched workflows.
- Release behavior will be verified during the normal release run.
