Phase 6: Restructure Ruby Gems to Final Monorepo Layout

Complete Phase 6 of the monorepo migration by restructuring the directory
layout so react_on_rails_pro is a sibling structure instead of a nested
subdirectory.

## Major Changes

### Directory Moves
- Moved `react_on_rails_pro/lib/react_on_rails_pro/` → `lib/react_on_rails_pro/`
  Both Ruby gems are now equal siblings under `lib/`
- Moved `react_on_rails_pro/spec/react_on_rails_pro/` → `spec/pro/react_on_rails_pro/`
  Pro specs now live alongside core specs in `spec/`
- Moved `react_on_rails_pro/react_on_rails_pro.gemspec` → `react_on_rails_pro.gemspec`
  Both gemspecs now at repository root
- Moved `react_on_rails_pro/CHANGELOG.md` → `CHANGELOG_PRO.md`
  Pro changelog now at root as sibling to main CHANGELOG.md
- Moved `react_on_rails_pro/lib/react_on_rails_pro.rb` → `lib/react_on_rails_pro.rb`
  Main require file now at lib/ root
- Moved Pro rake tasks from `react_on_rails_pro/lib/tasks/` → `lib/tasks/`
  (Renamed assets.rake to assets_pro.rake to avoid conflict)

### Configuration Updates
- Updated `Gemfile` to explicitly include both gemspecs:
  ```ruby
  gemspec name: "react_on_rails"
  gemspec name: "react_on_rails_pro"
  ```
- Updated `react_on_rails_pro.gemspec` paths:
  - Changed core version require from `../lib/` to `lib/`
- Updated `LICENSE.md` with final directory structure:
  - Added `lib/react_on_rails_pro/` for Pro Ruby code
  - Added `spec/pro/` for Pro specs
  - Added `react_on_rails_pro.gemspec` for Pro gemspec
- Updated `.rubocop.yml` exclusions for new Pro locations
- Updated `rakelib/release.rake` to reference new paths
- Updated `script/ci-changes-detector` patterns for new structure

### Path Updates
- Fixed require_relative paths in:
  - `spec/pro/react_on_rails_pro/assets_precompile_spec.rb`
  - `react_on_rails_pro/spec/dummy/spec/rails_helper.rb`

### What Remained in react_on_rails_pro/
The following remain in `react_on_rails_pro/` directory:
- `spec/dummy/` - Pro dummy app and test infrastructure
- `spec/execjs-compatible-dummy/` - Alternative test dummy
- Configuration files (.gitignore, .prettierrc, etc.)
- Documentation (docs/, README.md, CI_SETUP.md, etc.)
- Build infrastructure (Gemfile, Rakefile, package-scripts.yml, etc.)

This is intentional and documented in LICENSE.md.

## Benefits

✅ Clearer directory structure (equal siblings, not parent/child)
✅ Both gems buildable from root
✅ Licensing boundaries more obvious
✅ Matches monorepo plan target architecture
✅ Simpler import/require paths

## Test Plan

- [x] Both gems build successfully from root
- [x] Bundle install resolves both gems correctly
- [x] RuboCop passes with no violations
- [x] Prettier formatting passes
- [x] All paths updated in scripts and CI configs

## Migration Impact

**Users:** No impact - gem names and APIs unchanged
**Contributors:** Must update local clones - paths changed
