fix: Fix Twitter Search Logic and Add Galadriel Image Model

[dontAskVI]

Relates to:

N/A (No specific issue referenced)

Risks

Medium:

• Disabling or modifying the Twitter search functionality may affect users relying on it.
• Introducing a new image model provider (Galadriel) could introduce minor configuration or performance issues.

No major systemic risk anticipated; primarily feature enhancements and minor refactoring.

Background

What does this PR do?

• Fixes and refines the Twitter search functionality by commenting it out to prevent unintended searches and rate-limit issues.
• Introduces an image model for the Galadriel model provider.
• Cleans up code and removes unnecessary instances and calls (e.g., .getInstance()).
• Merges the latest changes from main to ensure the feature branch is up-to-date.

What kind of change is this?

• Improvements: Adjusting and refining existing search functionality.
• Features: Adding a new image model to the Galadriel model provider.
• Bug fixes: Addressing an issue with the Twitter search implementation.

Documentation changes needed?

• Minor updates to documentation may be needed to reflect that the Twitter search client is now commented out and that a new image model provider (Galadriel) is available.
• However, the core functionality changes are primarily internal. If documentation references the Twitter search or model providers, a brief note should be added.

Testing

Where should a reviewer start?

• Review packages/client-twitter/src/index.ts and packages/client-twitter/src/search.ts to see changes in the Twitter search logic.
• Review packages/core/src/models.ts to confirm the addition of the image model for the Galadriel provider.
• Check docs/docs/guides and docs/quickstart.md for any changes that may need follow-up documentation edits.

Detailed testing steps

1. Pull down the changes locally.
2. Run the application with the updated code.
3. Verify that the Twitter client no longer starts the search client by default (reducing rate limit concerns).
4. Confirm that the Galadriel image model is listed and accessible as expected.
5. Review logs and behavior to ensure no errors are introduced by the changes.

No special UI changes, so no screenshots required.
