What's Changed

MR: #368
Full Changelog: v0.95.6...v0.95.7

Addresses:

• fix: handle None command_paths without warning by @chrisnestrud in #367

Includes:

• TUI is default unless a user specfically unsets it
• Change command-paths: from a top-level key to a key under custom: (so the nested path is custom.command-paths) where both user defined command and prompt configs will live
• Add nester.py to make handling nested configurations simpler to implement and slightly more forgiving to users by making it hyphen and underscore agnostic, as well as handling fallback parameter names
• Add customizable system prompts through the custom.prompt-map configuration section
• Add Fireworks AI model provider by @chrisnestrud in #369
