chore: swap hit-area JS plugin for v4-native CSS @utility port

Replaces the custom `packages/config/tailwind-plugins/hit-area.js`
(v3-style `plugin()` + `matchUtilities`) with the Tailwind v4 port
from bazza.dev/craft/2026/hit-area (registry:
https://bazza.dev/r/hit-area, MIT).

The new version is pure CSS using `@utility hit-area-*` blocks with
`--value(number)` / `--value([*])` and integrates cleanly with v4's
CSS-first model — no JS plugin, no `matchUtilities` runtime.

Changes:

- Add `packages/config/tailwind-utilities/hit-area.css` with the vendored
  `@utility` blocks for `hit-area`, `hit-area-debug`, `hit-area-*`,
  `hit-area-t/b/l/r-*`, `hit-area-x-*`, `hit-area-y-*`.
- Delete `packages/config/tailwind-plugins/hit-area.js`.
- Remove `require('./tailwind-plugins/hit-area')` from
  `packages/config/tailwind.config.js`.
- Import the new CSS from every app CSS entry (studio, docs, www,
  design-system x2, ui-library, learn, lite-studio).

/**
* Hit Area plugin (Tailwind v3)
*
* Expands the interactive hit area of an element using a ::before pseudo-element,
* without affecting the visual layout.
*
* Usage:
* hit-area — adds invisible ::before that fills the element (0px expansion)
* hit-area-debug — same but with a visible blue dashed border overlay (hover turns green)
* hit-area-{n} — expands all sides by spacing value n (e.g. hit-area-2 → -0.5rem on each side)
* hit-area-x-{n} — expands left + right
* hit-area-y-{n} — expands top + bottom
* hit-area-t-{n} — expands top only
* hit-area-b-{n} — expands bottom only
* hit-area-l-{n} — expands left only
* hit-area-r-{n} — expands right only
*
* Arbitrary values are also supported, e.g. hit-area-[12px], hit-area-x-[1rem].
