docs: document intentional git scope limitation in workflow commands

The allowed-tools for create-plugin and create-marketplace commands only
include `Bash(git init:*)`. This is intentional to:
- Keep workflows focused on structure creation
- Let users control their own git workflow (commit messages, timing)
- Avoid assumptions about commit preferences

Added documentation explaining this and post-workflow git examples.

Fixes #136
