tsconfig scoped `types` to @cloudflare/workers-types only, but several files import Node builtins — src/lib/atproto/server/signed-cookie.ts uses node:crypto, and the atproto/scripts/* dev tools use node:fs / node:path / node:child_process. With no Node types loaded (and @types/node not even a dependency), `pnpm check` failed with 10 errors. Add @types/node@^22 (matches the Node 22 / pnpm 11 toolchain) and add "node" to the tsconfig types array. The Worker runs with nodejs_compat_v2, so these Node APIs are genuinely available at runtime — the types reflect reality rather than masking it. `pnpm check` now reports 0 errors (only pre-existing svelte state_referenced_locally warnings remain).
