Custom Session Environment File

What: New CLAUDE_ENV_FILE environment variable allows loading custom session environment scripts.

How to use:

export CLAUDE_ENV_FILE=/path/to/my-env-setup.sh
claude

Details:

• Scripts from CLAUDE_ENV_FILE are loaded before hook files from session-env directory
• Multiple sources can be combined (env file + hooks)
• Independent error handling - failures in one source don't prevent loading others
• Useful for personal environment configuration that doesn't belong in hooks
