feat: add Microsoft Foundry provider support (#684)

Browse Source 
* feat: add Azure AI Foundry provider support

Add support for Azure AI Foundry as a fourth cloud provider option alongside Anthropic API, AWS Bedrock, and Google Vertex AI.

Changes:
- Add use_foundry input to enable Azure AI Foundry authentication
- Add Azure environment variables (ANTHROPIC_FOUNDRY_RESOURCE, ANTHROPIC_FOUNDRY_API_KEY, ANTHROPIC_FOUNDRY_BASE_URL)
- Support automatic base URL construction from resource name
- Add validation logic with mutual exclusivity checks for all providers
- Add comprehensive test coverage (7 Azure-specific tests, 3 mutual exclusivity tests)
- Add complete Azure AI Foundry documentation with OIDC and API key authentication
- Update README to reference Azure AI Foundry support

Features:
- Primary authentication via Microsoft Entra ID (OIDC) using azure/login action
- Optional API key authentication fallback
- Custom model deployment name support via ANTHROPIC_DEFAULT_*_MODEL variables
- Clear validation error messages for missing configuration

All tests pass (25 validation tests total).

* refactor: rename Azure AI Foundry to Microsoft Foundry and remove API key support

- Rename all references from "Azure AI Foundry" to "Microsoft Foundry"
- Remove ANTHROPIC_FOUNDRY_API_KEY support (OIDC only)
- Update documentation to reflect OIDC-only authentication
- Update tests to remove API key test case

* docs: simplify Microsoft Foundry setup and remove URL auto-construction

- Link to official docs instead of duplicating setup instructions
- Remove automatic base URL construction from resource name
- Pass ANTHROPIC_FOUNDRY_BASE_URL as-is
