fix: hookify plugin imports broken by versioned cache path

[hmesfin]

Summary

The hookify plugin's Python hook scripts all fail with No module named 'hookify' because the import paths don't account for the versioned plugin cache directory structure.

Root cause: All hook scripts and core/rule_engine.py use from hookify.core.config_loader import ..., expecting a hookify Python package on sys.path. However, when installed via the plugin cache, the directory structure is:

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

The scripts add PLUGIN_ROOT (.../hookify/0.1.0/) and its parent (.../hookify/) to sys.path. But from hookify.core.config_loader requires a directory named hookify containing core/ somewhere on the path — the parent directory .../hookify/ only contains 0.1.0/, not core/.

Fix: Changed all from hookify.core. imports to from core. since PLUGIN_ROOT (which directly contains core/) is already on sys.path.

Test plan

• Install the hookify plugin and verify no Hookify import error: No module named 'hookify' messages appear on tool use
• Verify hookify rules still load and evaluate correctly

Pull request overview

This PR fixes a critical import error in the hookify plugin that prevented all hook scripts from functioning. The issue occurred because the plugin's import paths used from hookify.core.* which assumed a package structure that doesn't exist when the plugin is installed via the versioned cache directory (.../hookify/0.1.0/). The fix changes all imports to use relative imports (from core.*) since PLUGIN_ROOT (containing the core/ directory) is already added to sys.path.

Changes:

• Updated import statements from from hookify.core.* to from core.* across all hook scripts and the rule engine module
• Ensures compatibility with the versioned plugin cache directory structure
