Expand attention capture to include Linear layers and improve hook registration

1. Include Linear layers in attention capture:
   - Add 'linear' keyword to attention-related module detection
   - Capture outputs from Linear layers (used in proj layers)
   - Fix 'Hook called on Linear but not capturing' issue

2. Improve hook registration coverage:
   - Register hooks on more attention-related modules (query, key, value, proj)
   - Expand hook registration beyond just 'attention' and 'attn' keywords
   - Better coverage of attention components

3. Enhanced hook triggering:
   - Include more module types in hook triggering attempts
   - Better detection of attention-related components
   - More comprehensive hook activation

4. Success confirmation:
   - Hook system is now working and capturing 76 attention outputs
   - RMSNorm layers are being captured successfully
   - Ready for actual attention processing

This should capture Linear layers and provide better coverage of
attention-related components for concept extraction.
