feat(mousetrap): Add profile-based architecture and clickable lighter

Implement comprehensive profile-based system for selective mouse event
control with dynamic lighter and interactive toggling.

Features:
- Profile-based architecture (7 profiles: disabled, scroll-only,
  primary-click, scroll+primary, read-only, interactive, full)
- Mode-specific configuration (dashboard, pdf-view, nov)
- Dynamic keymap building based on current major mode
- Clickable modeline lighter (🐭 when off, 🪤 when on)
- Dynamic reconfiguration without Emacs reload
- Mode inheritance support via derived-mode-p

Profiles define which event categories are allowed:
- primary-click: Left mouse button only
- secondary-click: Middle and right buttons
- drags: Drag selections
- multi-clicks: Double and triple clicks
- scroll: Mouse wheel/trackpad scrolling

Default configuration:
- dashboard-mode: primary-click (left-click only)
- pdf-view-mode: full (all events)
- nov-mode: full (all events)
- Other modes: disabled (all events blocked)

Tests:
- 66 comprehensive tests across 5 test files
- Unit tests for profile lookup and keymap building
- Integration tests for mode switching and dynamic config
- Lighter functionality and click interaction tests
- All tests passing

Known issue:
- Dashboard-mode clicks blocked despite primary-click profile
- Documented in todo.org for investigation
