refactor: Reorganize FakeMUI by implementation type

Move FakeMUI content to appropriate root-level folders by implementation:

**React Components → components/fakemui/**
- 537 components (inputs, surfaces, layout, data-display, feedback,
  navigation, utils, atoms, lab, x, email, workflows)
- 416 SVG icons
- Full barrel exports in components/fakemui/index.ts

**QML Components → qml/**
- 104 Material Design 3 components (11 categories)
- 7 hybrid application views
- 8 desktop widgets
- qmldir module registration

**Python Bindings → python/fakemui/**
- 15 PyQt6 modules (120+ components)
- Full Python package structure with pyproject.toml

**SCSS/Styles → fakemui/** (renamed purpose)
- scss/ - Material Design 3 stylesheets
- styles/ - Component SCSS modules
- src/utils/ - Accessibility utilities
- index.ts now re-exports from components/fakemui/

This separation allows:
- React: import { Button } from '@metabuilder/components/fakemui'
- QML: import QmlComponents 1.0
- Python: from fakemui import Button, Card
- Backward compat: import { Button } from '@metabuilder/fakemui'
