Enhance install script to automatically install dependencies on first install

[Copilot]

Addresses the requirement to automatically install additional dependencies when no configuration file is present (first install).

Changes Made

The installation script now detects first-time installations and automatically sets up the complete ML Notes ecosystem:

🔍 First Install Detection

• Added is_first_install() function that checks for configuration file at ~/.config/ml-notes/config.json
• Uses the same XDG config path logic as the Go application for consistency
• Falls back to querying ml-notes config path if the binary is already available

📦 Automatic Dependency Installation

lil-rag Service Installation:

• Clones from https://github.com/streed/lil-rag
• Uses the repository's own install.sh script for proper installation
• Installs to /usr/local/bin alongside ml-notes
• Provides manual installation guidance if installation fails

pdftotext Command Installation:

• Linux: Installs poppler-utils via apt/yum/dnf/pacman package managers
• macOS: Installs poppler via Homebrew
• Automatically detects and uses available package manager
• Gracefully handles cases where package managers are unavailable

🛡️ Robust Error Handling

• Dependency installation failures are non-fatal - ml-notes still installs successfully
• Tracks failed installations and provides helpful manual installation guidance
• Users can install dependencies later without affecting core functionality

🔧 Enhanced Requirements

• Added git to required tools since it's needed for cloning lil-rag
• Maintains backward compatibility with existing installation flow

Example Output

On first install, users will see:

→ First install detected - setting up additional dependencies...
→ Installing first-time dependencies...
→ Installing pdftotext...
✓ pdftotext installed via apt-get
→ Installing lil-rag service...
→ Cloning lil-rag repository...
→ Running lil-rag installation script...
✓ lil-rag service installed successfully!
✓ First-time dependencies installed successfully!

If dependencies fail to install automatically, users get clear guidance:

⚠ Some dependencies could not be installed automatically: pdftotext lil-rag
→ You can install them manually later. ML Notes will still work without them.
→ For pdftotext: Install poppler-utils (Linux) or poppler (macOS)
→ For lil-rag: git clone https://github.com/streed/lil-rag.git && cd lil-rag && ./install.sh

On subsequent installs where configuration already exists, the script behaves exactly as before with no additional dependency installation.

This enhancement ensures users get a complete, ready-to-use ML Notes setup on first install while maintaining the reliability and simplicity of the existing installation process.

The trap is set inside the function scope and will only execute when the function exits, not when the script exits. If the script is interrupted or fails elsewhere after calling this function, the temporary directory may not be cleaned up. Move the trap outside the function or use a global cleanup mechanism.

[Copilot]

Using cd without saving the previous directory can leave the script in an unexpected location if subsequent operations fail. Consider using pushd/popd or executing the build command with the -C flag: go build -C \"$temp_dir/lil-rag\" -o lil-rag .

Suggested change

	cd "$temp_dir/lil-rag"
	if ! go build -o lil-rag .; then
	if ! go build -C "$temp_dir/lil-rag" -o lil-rag .; then

@copilot the lil-rag installation should use the install.sh script from the repository.

@copilot the lil-rag installation should use the install.sh script from the repository.

Updated the lil-rag installation to use the repository's own install.sh script instead of manually cloning and building. This ensures proper installation using the official method. Commit: 0c6eb90
