## Summary

- Add seamless integration with nvim-tree and neo-tree file explorers
- Implement @-mention functionality for files and directories via new ClaudeCodeTreeAdd and ClaudeCodeAdd commands
- Enable Claude to navigate and understand project file structures through visual selection
- Add support for new file creation in diff system with proper directory handling

## New Features

- **Tree Integration**: Context-aware <leader>as keybinding that sends text in normal buffers or adds files from tree explorers
- **@-mention Commands**:
  - `:ClaudeCodeTreeAdd` - Add selected files from tree explorers to Claude context
  - `:ClaudeCodeAdd <path> [start] [end]` - Add files/directories by path with optional line ranges
- **Enhanced Diff System**: Support for creating new files with automatic parent directory creation
- **Visual Selection**: Improved multi-file selection detection for both nvim-tree and neo-tree

## Technical Improvements

- Comprehensive test coverage with dedicated specs for @-mention functionality
- Improved error handling and user feedback for edge cases
- Enhanced build system with Nix integration for consistent development environment
- Code cleanup and maintainability improvements throughout codebase

## Breaking Changes

None - all changes are additive and backward compatible.

Fixes #14
Merge pull request #22 from coder/thomask33/nvim-tree-integration

feat: configurable auto-close and enhanced terminal architecture

* Adds  helper and propagates filetype to proposed buffers to restore syntax highlighting
* Cleans up duplicate code and stray newline
* Makes  CI-friendly by defining global  to avoid nested nix shells
* Updates unit tests to cover filetype propagation

Fix missing syntax highlighting in proposed diff view

Add automatic terminal provider detection that tries snacks first,
then falls back to native terminal silently. Update default config
to use "auto" provider for better user experience.

Partially addresses #16 by implementing the core mechanism to preserve
terminal processes when hiding windows. The native terminal provider now
sets bufhidden=hide before closing windows, preventing Neovim from
killing the terminal job when the window is closed.

- Add hide_terminal() helper that sets bufhidden=hide before window close
- Add show_hidden_terminal() to create windows for existing buffers
- Add is_terminal_visible() for buffer visibility detection
- Update toggle() logic to use hide/show instead of close/create
- Add comprehensive test suite for toggle behavior verification
- Optimize logger usage with module-level require

This change enables process preservation during window hiding, laying
the groundwork for full toggle behavior consistency with snacks provider.
