🤖 Augment PR Summary

Summary: Upgrades Tailwind CSS across the repo from v3.x to v4.1.18 (Dependabot).

Changes:

Bumps tailwindcss in apps/expo devDependencies to ^4.1.18.
Bumps tailwindcss in packages/tailwind-config devDependencies to ^4.1.18.
Regenerates pnpm-lock.yaml to resolve Tailwind v4 and updates affected dependency graph entries.
Removes Tailwind v3-specific transitive packages from the lockfile as they are no longer needed.

Technical Notes: This is a major-version upgrade (3 → 4), so any tooling/config that relies on Tailwind’s v3 APIs/plugins may need to be compatible with v4 (including packages that declare Tailwind as a peer dependency).

+    "tailwindcss": "^4.1.18",


@agent/tailwind-config still declares peerDependencies.tailwindcss as ^3.4.0 while this PR bumps the repo’s Tailwind to ^4.1.18, which will likely create a peer mismatch for consumers (e.g. apps/expo) and may lead to multiple Tailwind versions being installed. Consider aligning the peer range with the Tailwind major you intend to support.
