fix: correct installation method to project-local plugin

**Problem:**
- Previous commit (a302ca7) added `make install-plugin` that copied to ~/.claude/plugins/
- This breaks path references - plugins are designed to be project-local
- Wasted effort with install/uninstall commands

**Root Cause:**
- Misunderstood Claude Code plugin architecture
- Plugins use project-local `.claude-plugin/` directory
- Claude Code auto-detects when started in project directory
- No copying or installation needed

**Solution:**
- Remove `make install-plugin`, `uninstall-plugin`, `reinstall-plugin`
- Update README.md: Just `cd SuperClaude_Framework && claude`
- Remove ~/.claude/plugins/pm-agent/ (incorrect location)
- Simplify to zero-install approach

**Correct Usage:**
```bash
git clone https://github.com/SuperClaude-Org/SuperClaude_Framework.git
cd SuperClaude_Framework
claude  # .claude-plugin/ auto-detected
```

**Benefits:**
- Zero install: No file copying
- Hot reload: Edit TypeScript → Save → Instant reflection
- Safe development: Separate from global Claude Code
- Auto-activation: SessionStart hook runs /pm automatically

**Changes:**
- Makefile: Remove install-plugin, uninstall-plugin, reinstall-plugin targets
- README.md: Replace `make install-plugin` with `cd + claude`
- Cleanup: Remove ~/.claude/plugins/pm-agent/ directory

**Acknowledgment:**
Thanks to user for explaining Local Installer architecture:
- ~/.claude/local = separate sandbox from npm global version
- Project-local plugins = safe experimentation
- Hot reload more stable in local environment

 **Plugin not loading?**
-- Restart Claude Code completely

-- Run `/plugin` in Claude Code to verify installation
+# Verify you're in the project directory
-- Check that `.claude-plugin/plugin.json` exists in repository
+pwd  # Should show: /path/to/SuperClaude_Framework

+
+**Commands not working (/pm, /research, /index-repo)?**
+- Ensure you started `claude` from the SuperClaude_Framework directory
+- Check for errors in Claude Code output
+- Verify `.claude-plugin/plugin.json` has correct structure
