bug: cora auth login not scriptable despite --provider and --api-key flags

[ajianaz]

Description

cora auth login --provider zai --api-key <key> still enters interactive mode asking for provider selection and API key input. The --provider and --api-key flags are ignored.

Impact

• Cannot automate cora setup in CI/CD or Dockerfile
• Must use printf pipe as workaround, which is fragile

Expected Behavior

cora auth login --provider zai --api-key sk-xxx
# Should write to ~/.cora/auth.toml non-interactively

Workaround

Write ~/.cora/auth.toml directly:

[auth]
api_key = "sk-xxx"

Fixed by PR #203. cora auth login --provider zai --api-key test123 --force now works non-interactively. Also supports auto-detection of provider env vars (e.g. cora auth login --provider zai picks up ZAI_API_KEY automatically).
