Add local development infrastructure and documentation

Add essential development tools and documentation for Cthulhu development:

Development Scripts:
- build-local.sh: Local build and install to ~/.local
- clean-local.sh: Clean build artifacts and local installation
- test-local.sh: Test local installation

Documentation:
- README-REMOTE-CONTROLLER.md: D-Bus service API documentation
- README-DEVELOPMENT.md: Development workflow documentation
- .gitignore: Updated with local build artifact patterns

These tools enable efficient local development without system-wide installation
and provide proper documentation for the D-Bus remote control capabilities.

+# Cthulhu Development Guide
+
+## Local Development Build
+
+To develop Cthulhu without overwriting your system installation, use the provided build scripts:
+
+### Building Locally
+
+```bash
+# Build and install to ~/.local
+./build-local.sh
+
+# Clean build and rebuild everything
+./build-local.sh --clean
+```
+
+This installs Cthulhu to `~/.local/bin/cthulhu` without touching your system installation.
+
+### Testing the Local Build
+
+```bash
+# Test the local installation
+./test-local.sh
+
+# Run the local version directly
+~/.local/bin/cthulhu --version
+```
+
+### Running Local Cthulhu
+
+```bash
+# Method 1: Direct path
+~/.local/bin/cthulhu
+
+# Method 2: Add to PATH (add to ~/.bashrc)
+export PATH="$HOME/.local/bin:$PATH"
+cthulhu
+```
+
+### Cleaning Up
+
+```bash
+# Clean build artifacts only
+./clean-local.sh --build-only
+
+# Remove local installation only  
+./clean-local.sh --install-only
+
+# Clean everything (build artifacts + local installation)
+./clean-local.sh
+```
+
+## D-Bus Remote Controller
+
+Cthulhu now includes a D-Bus service for remote control:
+
+- **Service**: `org.stormux.Cthulhu.Service`
+- **Path**: `/org/stormux/Cthulhu/Service`
+- **Requires**: `dasbus` library (should be installed)
+
+### Testing D-Bus Service
+
+```bash
+# Start Cthulhu with D-Bus service
+~/.local/bin/cthulhu
+
+# In another terminal, test the service
+busctl --user call org.stormux.Cthulhu.Service /org/stormux/Cthulhu/Service org.stormux.Cthulhu.Service GetVersion
+
+# Present a message via D-Bus
+busctl --user call org.stormux.Cthulhu.Service /org/stormux/Cthulhu/Service org.stormux.Cthulhu.Service PresentMessage s "Hello from D-Bus"
+```
+
+## Development Workflow
+
+1. **Make changes** to the code
+2. **Build locally**: `./build-local.sh`
+3. **Test**: `./test-local.sh`
+4. **Run**: `~/.local/bin/cthulhu`
+5. **Clean when done**: `./clean-local.sh --build-only`
+
+## Git Repository Management
+
+The `.gitignore` file is configured to exclude:
+- Build artifacts (`configure`, `Makefile`, etc.)
+- Generated Python files (`cthulhu_bin.py`, `cthulhu_i18n.py`, etc.)
+- Python bytecode (`*.pyc`, `__pycache__/`)
+
+Before committing:
+```bash
+# Clean build artifacts to avoid committing them
+./clean-local.sh --build-only
+
+# Check what will be committed
+git status
+```
+
+## Dependencies
+
+- **Runtime**: python3, pygobject-3.0, pluggy, AT-SPI2
+- **Build**: autotools, gettext, intltool
+- **Optional**: dasbus (for D-Bus service), BrlTTY, speech-dispatcher
+
+Install build dependencies on Arch Linux:
+```bash
+sudo pacman -S autoconf automake intltool gettext python-dasbus
+```
