fix(installer): default SCRIPT_VERSION to main instead of pinned tag (#173)

The bob platform skills (evolve-lite:learn, evolve-lite:recall) were added
after v1.0.6, so the pinned tag causes bob lite installs to fail with
FileNotFoundError. Default to main so the installer always pulls the
latest source tree.

Fixes #171
