feat: v0.1.4 — QuickJS integration for inline JavaScript data extraction

Embeds QuickJS (rquickjs) to execute inline <script> tags and extract
data hidden in JavaScript variable assignments. Captures window.__*
objects like __preloadedData (NYTimes), __PRELOADED_STATE__ (Wired),
and self.__next_f (Next.js RSC flight data).

Results:
- NYTimes: 1,552 → 4,162 words (+168%)
- Wired: 1,459 → 9,937 words (+580%)
- Zero measurable performance overhead (<15ms per page)
- Feature-gated: disable with --no-default-features for WASM

Smart text filtering rejects CSS, base64, file paths, code strings.
Only readable prose is appended under "## Additional Content".
