Rahim 0486765848 feat(compiler): configurable @property handling for --tw-* slots
Tailwind registers internal slots (`--tw-content`, `--tw-shadow`, …) via
`@property` rules that supply their defaults. `decompose` dropped those
rules, so utilities that reference a slot without setting it locally —
notably `after:*`/`before:*` emitting `content: var(--tw-content)` — left
a dangling reference that resolves to nothing and suppresses the
pseudo-element.

`decompose` now captures the `@property` registrations, and `emitCss`
gains a `properties` option to handle them, configurably:

  - `mode: 'emit'`   — emit `@property` rules for referenced slots,
    preserving Tailwind's typed defaults.
  - `mode: 'inline'` — substitute each slot's `initial-value` into the
    values that reference it (a superset of `inlineVars` for the matched
    slots), so the output is fully self-contained.
  - `resolve(name, captured)` hook — override or supply a slot's config
    (initial-value / syntax / inherits), or register one Tailwind didn't.
  - `match` — restrict handling to matching names (default `/^--tw-/`).

`tailwindPlugin` forwards `properties` through its `onCss` path. Adds 9
tests (capture, emit, inline, resolve override, match, back-compat,
plugin e2e). Compiler suite: 178 passing.
