fix(databricks): address PR review feedback

- Move Databricks scripts from packages/core/script/ to providers/databricks/scripts/
  with their own package.json; remove @databricks/sdk-experimental from packages/core
- Add Zod runtime validation to fetchFilteredGatewayRoutes (replaces unsafe cast)
- Replace isOpenAIcompatible boolean with openAICompatiblePackages Set in schema.ts
- Clarify provider.toml env comment with PAT vs OAuth M2M auth modes
- Shorten dense root README.md entry to a one-liner linking to provider README
- Add bun.lock to .gitignore
- Add databricks-claude-opus-4-7 model TOML
