fix: Resolve theme system crashes and functionality issues

- Fix Sol2 lambda binding for create_and_register_theme method
  * Added missing EditorCore& first parameter to prevent empty theme names
- Add set-theme command to defaults.hpp as fundamental command
- Fix active_theme property access in lua/themes/themes_init.lua
  * Changed editor.theme_manager.active_theme to :active_theme() function calls
- Refactor themes from hardcoded C++ to individual Lua files in lua/themes/
- Remove old themes.lua file and C++ theme factory methods
- All theme functionality now working: listing, switching, cycling, keybindings

Resolves C-x t l crash and enables full theme management via M-x set-theme
and C-x t keybinding sequences. Six themes available: default, dracula,
everforest-dark, gruvbox-light, nord, solarized-dark.

 - ✅ **GTK Enhancements**: (Fully completed - Phase A).
 - ✅ **Minibuffer & Command System**: Minibuffer core logic, history management, and completion are fully centralized and integrated with the Command System (Phases Z and C completed).
     - **Advanced Completion UI**: Completed (Implemented popup completion window with descriptions and better visual feedback).
-- ✅ **Theme System**: Comprehensive and functional.
+- ✅ **Theme System Refactoring**:
+    - [x] Implemented `editor:create_and_register_theme` Lua API to allow theme definition from Lua.
+    - [x] Factored all hardcoded C++ themes (`default`, `everforest-dark`, `dracula`, `solarized-dark`, `nord`, `gruvbox-light`) into individual Lua files (`lua/themes/*.lua`).
+    - [x] Removed hardcoded theme definitions and factory methods from C++ (`src/theme.cpp`, `include/lumacs/theme.hpp`).
+    - [x] Updated `init.lua` to load the new individual theme files and `themes_init.lua`.
+    - [x] **RESOLVED**: Fixed theme functionality issues. Root causes were:
+        - **Sol2 lambda binding issue**: The `create_and_register_theme` method binding was missing the `EditorCore&` first parameter, causing empty theme names.
+        - **Missing set-theme command**: Added `set-theme` command to `defaults.hpp` as a fundamental command that theme switching functions depend on.
+        - **Active theme access issue**: Fixed incorrect `active_theme` property access in `lua/themes/themes_init.lua` - changed from `editor.theme_manager.active_theme` to `editor.theme_manager:active_theme()` function calls.
+        - **Theme system fully functional**: All 6 themes (default, dracula, everforest-dark, gruvbox-light, nord, solarized-dark) load correctly, theme switching works via `M-x set-theme`, `C-x t` keybindings work (including `C-x t l` for listing), and theme cycling is operational.
 - ✅ **Phase 15 Polishing**: Successfully addressed GTK Cleanup and Modeline Refactor.
 - ✅ **Plugin Management**: Implemented dynamic loading and lifecycle management of Lua plugins.
 - ✅ **Lua Debugging**: Integrated basic remote debugging support for Lua scripts via MobDebug.
