fix: fixed stats dashboard asset serving for bundled CLI distributions

- Fixed npm CLI bundling by invoking `generate-client-bundle.ts --generate` before build and `--reset` after.
- Added `PI_BUNDLED` handling in `packages/stats/src/server.ts` and switched bundled distributions to embedded assets.
- Decoded embedded archives via `decodeEmbeddedClientArchive` and treated legacy placeholder content as missing.
- Handled missing dashboard source/build directories as ENOENT during mtime scans to avoid startup crashes.
- Extended `--smoke-test` to start the stats server and validate dashboard HTML contains expected asset markers.
