omc setup should support --no-plugin flag for local skill installation and development

[pgagarinov]

Summary

omc setup (CLI) installs hooks, agents, and HUD but explicitly skips skills with the message "Skipping slash command installation (all commands are now plugin-scoped skills)". This creates a gap for users who install via npm install -g without the plugin system, and makes it impossible to test local skill changes without going through the plugin cache.

Current behavior

• omc setup installs: hooks, agents, HUD wrapper, CLAUDE.md
• omc setup skips: skills (assumes plugin system handles them)
• Plugin system serves skills from ~/.claude/plugins/cache/omc/..., not from the working copy
• README presents plugin and npm as equivalent install methods, but they're not: npm gives the CLI without skills, plugin gives skills without the CLI

Problem

1. npm-only users have no skills — /omc-setup, /ralph, /ultrawork etc. are unavailable unless the plugin is enabled
2. Local skill development is blocked — editing skills/ in a cloned repo has no effect until changes are delivered via the plugin cache. There's no way to test skill changes locally without hacking the cache or pointing a directory marketplace at the repo
3. README is confusing — it suggests npm and plugin are alternative install methods, but each is incomplete without the other

Proposed solution

Add a --no-plugin (or --dev) flag to omc setup that:

• Copies skills from the package's skills/ directory to ${CLAUDE_CONFIG_DIR:-~/.claude}/skills/
• Auto-detects when no plugin is enabled and falls back to file-based skill installation
• Enables a local development workflow where skill edits take effect immediately

This would make npm install -g a truly self-contained install path and unblock skill development/debugging without the plugin system.

Investigating now. I'm opening a dedicated fix session/worktree to verify the current setup/install split and wire a scoped fix for the no-plugin/local-skill-install path. I'll follow up here with the PR once it's ready.
