When using `gt sling <formula> --on <bead>`, the command now properly
instantiates the formula as a molecule and bonds it to the target bead:
1. Cook the formula (ensures proto exists)
2. Create wisp with feature variable from bead title
3. Bond wisp to original bead (creates compound)
4. Hook the compound root (not bare bead) to target agent
This enables the "shiny" workflow (design→implement→review→test→submit)
to be applied to existing bugs/features, ensuring polecats complete all
phases including the code review step.
Example:
gt sling shiny --on gt-abc gastown
# Creates shiny molecule, bonds to gt-abc, slings compound to polecat
