Promote 0.1.15 to the current stable Walter On-Prem release
Add Azure OpenAI support for OpenAI-compatible v1 endpoints that use API-key authentication
Tighten setup and admin LLM validation so configured chat and embedding models must pass live provider probes before Walter accepts them
Operator notes
bin/walter-onprem upgrade now resolves to 0.1.15 for existing 0.1.x installs
Azure OpenAI deployments should be entered by deployment name; Walter validates those names with a real inference probe instead of trusting the provider model catalog
No manifest or bundle refresh flags are required for this upgrade, but operators should re-test LLM settings if they previously saved model names that were never live-validated
