Code Review

This pull request updates the documentation for the feature compatibility matrix to improve its precision. The changes correctly adjust the compatibility status for pooling from 'full' to 'partial' to match the accompanying footnote, and add a new footnote to clarify LoRA support for multimodal models. These changes enhance the accuracy and clarity of the documentation. I have reviewed the changes and found no issues of high or critical severity.

👋 Hi! Thank you for contributing to the vLLM project.

💬 Join our developer Slack at https://slack.vllm.ai to discuss your PR in #pr-reviews, coordinate on features in #feat- channels, or join special interest groups in #sig- channels.

Just a reminder: PRs would not trigger full CI run by default. Instead, it would only run fastcheck CI which starts running only a small and essential subset of CI tests to quickly catch errors. You can run other CI tests on top of those by going to your fastcheck build on Buildkite UI (linked in the PR checks section) and unblock them. If you do not have permission to unblock, ping simon-mo or khluu to add you in our Buildkite org.

Once the PR is approved and ready to go, your PR reviewer(s) can run CI to test the changes comprehensively before merging.

To run CI, PR reviewers can either: Add ready label to the PR or enable auto-merge.
