Subject: [PATCH] fix: handle missing config file without crashing

Auto-create default config file and parent directories when
~/.config/task-cli/config.yaml does not exist. Gracefully fall back
to defaults on malformed config content.

Fixes FileNotFoundError crash when running commands before config is
initialized.

Closes #2
