External packages (pi-rtk, pi-context, pi-agent-browser, etc.) import from
the original @mariozechner/* scope which GSD forked to @gsd/*. Add aliases
in both jiti resolution paths (virtualModules for Bun, getAliases for Node)
so these packages resolve correctly without manual workarounds.
Closes#161
