fix(bob): honor legacy_commands in ai_skills persistence and add bob to ALWAYS_SLASH_AGENTS

- init.py: suppress ai_skills=True when --legacy-commands is passed so
  extensions and presets target .bob/commands, not .bob/skills
- _invocation_style.py: add 'bob' to ALWAYS_SLASH_AGENTS so init next-steps
  and hook invocations always show /speckit-<name> (skills is the default
  layout; no ai_skills flag required)
