fix: bundle workspace dependencies for npm registry installs

Workspace packages (@gsd/pi-agent-core, @gsd/pi-ai, @gsd/pi-coding-agent,
@gsd/pi-tui) are included in the published tarball via the "files" field but
are not resolvable by Node because npm does not recreate workspace symlinks
when installing from the registry. This causes "ERR_MODULE_NOT_FOUND: Cannot
find package '@gsd/pi-coding-agent'" on fresh installs.

Add workspace packages to both "dependencies" and "bundleDependencies" so npm
packs them into node_modules/ within the tarball and installs them correctly.
