feat: add name field injection for forgecode agent

Forgecode requires both 'name' and 'description' fields in command
frontmatter. This commit adds automatic injection of the 'name' field
during command generation for forgecode.

Changes:
- Python (agents.py): Add inject_name: True to forgecode config and
  implement name injection logic in register_commands
- Bash (create-release-packages.sh): Add post-processing step to inject
  name field into frontmatter after command generation

This complements the existing handoffs stripping fix (d83be82) to fully
support forgecode command requirements.
