fix: unblock CI typecheck, sherif and nix build gates

- Guard the optional codePointAt results in the cron jitter hash and the
  legacy-input detector so tsgo's strict checks pass.
- Type the accent and color-scheme value sets as ReadonlySet instead of
  readonly string[], which vue-tsc rejected on every .has() call.
- Skip the private apps/vscode workspace in sherif; it is pinned to the
  VS Code host runtime and is intentionally behind the other apps.
- Refresh the pnpmDeps hash in flake.nix to match the current lockfile.
