`copilotkit-upgrade` was the one skill the v2 migration skipped. It
routed users to packages that don't exist, so following it produces a
non-installable app.
Root cause: the skill was generated against a non-existent
`packages/v1/*` / `packages/v2/*` layout. The repo is flat and v2 ships
from the `/v2` subpath of the same packages.
## Fix (pure docs)
Corrected every package/import reference across `SKILL.md` plus the
three reference files against the live exports maps:
| Phantom in skill | Real target |
| --- | --- |
| `@copilotkit/react` | `@copilotkit/react-core/v2` |
| `@copilotkit/agent` | `@copilotkit/runtime/v2` (`BuiltInAgent`) |
| bare `@copilotkit/runtime` for v2 APIs | `@copilotkit/runtime/v2` |
| `createCopilotEndpointExpress` (doesn't exist) |
`createCopilotExpressHandler` (`@copilotkit/runtime/v2/express`) |
Also fixed the install commands and regenerated `sources.md` against the
real flat layout.
## Verification
Grep sweep shows zero remaining phantom references, and every v2 symbol
the skill now cites was confirmed to exist in the live source barrels.
