feat: Change installation directory to ~/.claude/commands/sc/

- Updated default installation path from ~/.claude/commands/ to ~/.claude/commands/sc/
- This maintains the /sc: namespace through directory organization
- Updated install_commands() default path in install_commands.py
- Updated CLI --target default in main.py to ~/.claude/commands/sc
- Updated list_installed_commands() to look in sc subdirectory
- All tests passing (70 passed, 1 skipped)
- Verified real installation: commands now install to ~/.claude/commands/sc/

Commands retain their /sc: prefix through name field in frontmatter:
- /sc:research - Deep web research
- /sc:index-repo - Repository indexing
- /sc:agent - Specialized AI agents
- /sc:recommend - Command recommendations
- /sc - Main help/dispatcher
