feat: restructure keymaps and fix Lua configuration

- Restructure keymaps into modular folder system
  - Create keymaps/ folder with organized files
  - Separate keymaps by category (general, personal, lsp, telescope, plugins)
  - Auto-loading system for better maintainability

- Fix Lua configuration issues
  - Add compatibility layer for deprecated APIs
  - Fix snacks.nvim configuration
  - Disable latex support in render-markdown
  - Improve LSP configuration

- Enhance function navigation
  - Restore and improve LSP keymaps
  - Add comprehensive Telescope integration
  - Fix conflicting keymaps

- Improve overall Neovim setup
  - Better options configuration
  - Enhanced plugin configurations
  - Cleaner code organization
