feat(init): add IDE restart instruction after init (Fission-AI#323)

Add prominent restart instruction in success message to inform users
they need to restart their IDE/coding tool for slash commands to appear.
Applies to all tools when slash commands are created or refreshed.

Also updates cli-init spec to document the restart instruction requirement.
