ci: strip to lint/vulns only, fix Post-step node toolcache

Remove test and race jobs until lint + vulns are fully green.
The node:22-alpine3.21 base image ships node at /usr/local/bin but
actions/setup-node expects it in the toolcache at /opt/hostedtoolcache.
Create a symlink so all Post-action cleanup steps (cache-save) find
node and don't exit 255.
