feat: Claude Desktop configuration support for Linux and Windows

[tomasohara]

adds Claude Desktop configuration support for Linux and Windows (#164)

[jonigl]

Suggested change

	CONFIG_DIR = os.path.join(APPDATA, 'Claude', 'claude_desktop_config.json')
	CONFIG_DIR = os.path.join(APPDATA, 'Claude')

This suggestions avoid repeating the filename for the CONFIG_DIR.
Because in line 18 already concatenate the json filename:

DEFAULT_CLAUDE_CONFIG = os.path.join(CONFIG_DIR, "claude_desktop_config.json")

Hey @tomasohara when you get a chance, please check my suggestions

[jonigl]

Suggested change

	APPDATA = os.environ['APPDATA']
	APPDATA = os.environ.get('APPDATA', os.path.expanduser('~/AppData/Roaming'))

using .get to avoid KeyError if the envar is not present. And adding fallback just in case

[tomasohara]

Good point about using get.

Note that when researching the location, Claude suggested the following code. I was going to use it, but it introduces a new dependency.

from platformdirs import user_config_dir
...
config_dir = user_config_dir("Claude", roaming=True)
DEFAULT_CLAUDE_CONFIG = os.path.join(config_dir, "claude_desktop_config.json")

Yeah, adding a new dependency for this looks like an overkill. Feel free to go ahead and commit the suggestions or propose a different approach
