Deno no longer runs anything after the node runtime and vitest moves: - delete deno.lock, the deno.jsonc files and the bun-to-deno migration plan - drop setup-deno from the check, dx, migrate, proto-check and test workflows - drop deno from devbox; the lock also picks up the node 26.8.1 entry the runtime PR bumped in devbox.json but never locked - remove deno compile artifacts from the server and workflows .gitignore - reword comments and docs that pointed at deno (toolchain, NODE_ENV folding, edge-safety, import-map format) Verified with a failing deno shim first on PATH: pnpm verify, both tsdown builds, migrate and the full test run pass with no deno invocation.
