Summary

Normalizes Databricks hosts at the generated transport boundary so every modular service client accepts scheme-less ClientOptions.host, configuration-profile host, and DATABRICKS_HOST values.

Why

Generated clients previously concatenated the configured host into request URLs without ensuring it was absolute. A bare host such as the value commonly supplied through DATABRICKS_HOST therefore reached fetch as a relative URL and failed with TypeError: Invalid URL, forcing consumers such as AppKit to normalize the host themselves.

What changed

Interface changes

• ClientOptions.host now documents that HTTPS is used when the scheme is omitted; its TypeScript shape is unchanged.

Behavioral changes

• Trim host input, prepend https:// when no HTTP(S) scheme is present, preserve explicit HTTP(S), and remove the trailing slash.
• Pass the normalized host to default credentials so authentication discovery and API requests use the same endpoint.

Internal changes

• Regenerate all 84 service transports from the updated generator and add table-driven coverage for environment, explicit, HTTPS, and local HTTP hosts.
• Record the fix in the options package changelog.

How is this tested?

npm run build, npm run lint, npm run format:check, npm run typecheck, and npm test pass. The 298 browser tests in the browser-bearing packages also pass against the system-installed Chrome.
