Migrate from Projectile to built-in project.el and fix Org mode

Major changes:
- Replace Projectile with built-in project.el for project management
- Add comprehensive Org mode configuration with TODO keywords and org-kanban support
- Fix multiple parsing errors and keybinding conflicts

Key improvements:
- Faster startup with built-in project.el (no external dependencies)
- Better integration with Eglot LSP client
- Proper Org TODO keyword highlighting and kanban column ordering
- Fixed unbalanced parentheses in init-completion.el and init-utils.el
- Resolved keybinding conflicts (C-c d g → C-c G d, removed C-u C-c C-r)
- Updated all file paths in init-utils.el to use lisp/ subdirectory

The configuration now loads cleanly without errors and maintains backward
compatibility with most Projectile keybindings (C-c p prefix) while also
supporting the standard project.el bindings (C-x p prefix).
