Honor [__settings__].default_profile in api, bundle, and auth token

 ### CLI
 
 * Added `databricks aitools` command group for installing Databricks skills into your coding agents (Claude Code, Cursor, Codex CLI, OpenCode, GitHub Copilot, Antigravity). Skills are fetched from [github.com/databricks/databricks-agent-skills](https://github.com/databricks/databricks-agent-skills) and either symlinked into each agent's skills directory or copied into the current project. Use `databricks aitools install` to set up, `update` to pull newer versions, `list` to see what's available, and `uninstall` to remove them.
+* `[__settings__].default_profile` is now consulted as a fallback by `databricks api`, `databricks auth token`, and bundle commands when neither `--profile` nor `DATABRICKS_CONFIG_PROFILE` is set. `databricks auth token` continues to give precedence to `DATABRICKS_HOST` over `default_profile`. For bundle commands, `default_profile` only applies when the bundle does not pin its own `workspace.host`.
 
 ### Bundles
 * Make sure warnings asking for approval are understood by agents ([#5239](https://github.com/databricks/cli/pull/5239))
