fix(hookify): fix Python import path for cached plugins

[saasom]

Summary

Fixes the hookify plugin's Python import path issue that occurs when plugins are cached by Claude Code.

The Problem:
When Claude Code caches plugins, it creates a versioned directory structure:

~/.claude/plugins/cache/claude-code-plugins/hookify/0.1.0/core/config_loader.py

The original code tried to import using package-style imports:

from hookify.core.config_loader import load_rules

This fails because:

1. CLAUDE_PLUGIN_ROOT points to .../hookify/0.1.0/
2. The code adds parent_dir (.../hookify/) to sys.path
3. Python looks for a hookify directory with core/ inside it
4. But the actual structure is hookify/0.1.0/core/ - the version directory breaks the package path

The Fix:
Since PLUGIN_ROOT is already added to sys.path and points directly to the versioned directory (.../0.1.0/), we can import directly:

from core.config_loader import load_rules

This works because core/ is a direct child of PLUGIN_ROOT.

Files Changed

• plugins/hookify/hooks/stop.py - Updated imports and path setup
• plugins/hookify/hooks/pretooluse.py - Updated imports and path setup
• plugins/hookify/hooks/posttooluse.py - Updated imports and path setup
• plugins/hookify/hooks/userpromptsubmit.py - Updated imports and path setup
• plugins/hookify/core/rule_engine.py - Updated internal imports

Test Plan

• Verified imports work with simulated cached plugin structure
• Manual testing with fresh plugin installation
• Verify all hook events (Stop, PreToolUse, PostToolUse, UserPromptSubmit) work correctly

Reproduction Steps (for the original bug)

1. Install the hookify plugin via marketplace
2. Observe error on Stop hook: Hookify import error: No module named 'hookify'
3. Check ~/.claude/plugins/cache/claude-code-plugins/hookify/ to see versioned structure
