- setup-node action: use 'yarn install --immutable' (Yarn 4 syntax) - unit.yml: drop Node 16 from matrix (Yarn 4 requires Node >=18), bump checkout to v6 - bump webpack to ^5.107.2
Node 16 can't run Yarn 4 or tsx (both require Node >=18). Run the unit suite on Node 16 in a dedicated job: install deps on Node 24, then switch to Node 16 and run mocha through @babel/register instead of tsx.
