Remove redundant Tailwind CSS guidelines (#661)

* Remove redundant Tailwind CSS guidelines and update skill description

When we first added skill support, skill triggering wasn't reliable enough, so we added a core.blade.php guideline that duplicated instructions already in the Tailwind CSS skill — things like always use search-docs and activate tailwindcss-development for Tailwind tasks. This burned extra context tokens on every request.

We now have an eval system for testing and improving skill descriptions, so they trigger reliably. This means the redundant guideline file is no longer needed.

Approach

- Remove the redundant core.blade.php guideline that duplicated the Tailwind CSS skill's own instructions

- Refine the skill description to be more specific about Tailwind CSS scoping, validated through trigger evals

* Fix documentation line in Tailwind CSS skills
