Support for Databricks Foundation Model APIs provider

Add Databricks as a new provider to support Foundation Model APIs.

Problem:
Databricks users cannot use opencode with their Databricks workspace's Foundation Model APIs (Claude, Llama, GPT, Gemini models) which are available as pay-per-token endpoints.

Proposed solution:

Add Databricks provider with OpenAI-compatible endpoint support
Support multiple auth methods: PAT tokens, OAuth M2M, Azure AD Service Principal
Include default model definitions for common Foundation Model API endpoints
Add auth command guidance for Databricks authentication setup

Verification:

Unit tests for provider configuration parsing
Tests for auth precedence and URL handling
