`verify:runtime-package` could not pass on a channels release PR. `pnpm pack`
rewrites the runtime's `workspace:` ranges to the workspace's current version,
so on a release PR the temp consumer tried to resolve the freshly-bumped
`@copilotkit/channels-intelligence` from npm — the version this very PR is
about to publish. It failed `unit (20.x)` by construction on #6185 and #6025.
Apply the fix `verify-channels-umbrella` already uses: pack the whole
first-party `workspace:` closure locally and pin it through pnpm `overrides`.
The packing helpers move to `lib/pack-workspace.ts` so both scripts share one
implementation instead of duplicating it.
The contract is unchanged: the packed runtime must still declare
channels-intelligence as a real dependency, and it must still load through
both ESM and CJS.
