Greptile Summary

Changed the config file path resolution for non-Windows systems from dirs::config_dir() to dirs::home_dir() + .config. This standardizes the config location to ~/.config/s2/config.toml for all Unix-like systems.

Key Changes:

• Linux: No change - still uses ~/.config/s2/config.toml
• macOS: Breaking change - moves from ~/Library/Application Support/s2/config.toml to ~/.config/s2/config.toml
• Windows: No change - still uses %APPDATA%\s2\config.toml

Concerns:

• This breaks existing macOS installations without migration logic or documentation
• macOS convention is to use ~/Library/Application Support for app configs, not ~/.config
• No migration path for existing users to move their configs

Confidence Score: 3/5

• This PR introduces a breaking change for macOS users without migration support
• The code change itself is simple and safe from a compilation perspective, but it breaks macOS convention and existing user configs without providing migration logic or clear documentation. The change may be intentional to standardize paths, but lacks the necessary support for a smooth transition.
• src/config.rs requires attention for macOS compatibility and migration strategy
