Subject: [PATCH] Mark the package as targeting Tailwind CSS v3

For Tailwind v4, use canonical_tailwind. This adds a README banner, updates
the mix.exs description, and adds a CHANGELOG entry so the v3 scope and the
v4 pointer surface on GitHub, hex.pm, and hexdocs.

Docs and metadata only, no code changes.
