Summary of Changes

Hello, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request streamlines the configuration for Looker prebuilt tools by consolidating the source definition for looker and looker-dev. This change reduces redundancy in the codebase and simplifies the setup process for users, ensuring that both development and production Looker tools leverage a single, consistent source configuration. The update also includes corresponding documentation adjustments to guide users through the revised setup.

Highlights

Consolidated Looker Source Definition: The looker-dev prebuilt tool now shares its source definition with the looker prebuilt tool, eliminating redundant configuration.
Documentation Updates: User-facing documentation has been updated to reflect the new shared source configuration, guiding users to include both looker and looker-dev in their prebuilt tool commands and configurations.
Simplified looker-dev.yaml: The internal/prebuiltconfigs/tools/looker-dev.yaml file has been refactored to remove its own sources definition and now points all its tools to the looker-source.

Changelog

docs/LOOKER_README.md
- Updated the npx command example to include looker-dev alongside looker for prebuilt tool usage.
- Modified the mcpServers configuration example to specify looker,looker-dev in the --prebuilt arguments.
docs/en/reference/prebuilt-tools.md
- Removed the detailed list of environment variables previously associated with looker-dev.
- Added a note clarifying that looker-dev must be used in combination with looker.
internal/prebuiltconfigs/tools/looker-dev.yaml
- Removed the entire sources section, eliminating the looker-dev-source definition.
- Updated all tool definitions (e.g., health_pulse, health_analyze, dev_mode, get_projects, etc.) to reference looker-source instead of looker-dev-source.

Thank you!

Will also start thinking about refactoring the yaml file. Could potentially merge the 2 yaml into one and separate looker_prod vs looker_dev via toolsets?
