fix: harden resource limits, path safety, and WASM build (#46)
Security audit follow-up across the workspace:

- webclaw-core: keep the crate WASM-safe. quickjs/rquickjs is now a
  cfg(not(wasm32)) target dependency and the extraction entry point uses
  a direct call on wasm instead of spawning a thread, so it builds and
  runs on wasm32 with or without default features.
- webclaw-core: bound the structured-data scrubber recursion (depth cap)
  so deeply nested attacker JSON-LD / __NEXT_DATA__ cannot exhaust the
  stack.
- webclaw-fetch: stream the response body with a running ceiling so a
  small highly compressed payload cannot inflate to gigabytes in memory;
  redact user:pass@ from proxy URLs before they reach error strings.
- webclaw-cli: contain output filenames inside the chosen directory
  (reject .. / absolute, drop traversal path segments), run --webhook
  URLs through the public-URL SSRF guard, clamp --watch-interval to >=1s,
  and make research slug truncation char-safe.
- webclaw-mcp: char-safe slug truncation (no multibyte slice panic).
- setup.sh / deploy/hetzner.sh: replace eval on read input with
  printf -v, and mask auth key / API token in console output.
- CI: enforce the wasm32 build invariant for webclaw-core.

Tests added for every behavioral change. Bump to 0.6.3 + CHANGELOG.

failure on the merge commit.

74bac87435 fix: prevent stack overflow on deeply nested HTML pages
Pages like Express.co.uk live blogs nest 200+ DOM levels deep, overflowing
the default 1 MB main-thread stack on Windows during recursive markdown
conversion.

Two-layer fix:

1. markdown.rs: add depth parameter to node_to_md/children_to_md/inline_text
   with MAX_DOM_DEPTH=200 guard — falls back to plain text collection at limit

2. lib.rs: wrap extract_with_options in a worker thread with 8 MB stack so
   html5ever parsing and extraction both have room on deeply nested pages

Tested with Express.co.uk live blog (previously crashed, now extracts 2000+
lines of clean markdown) and drudgereport.com (still works correctly).

8d29382b25 feat: extract __NEXT_DATA__ into structured_data
Next.js pages embed server-rendered data in <script id="__NEXT_DATA__">.
Now extracted as structured JSON (pageProps) in the structured_data field.

Tested on 45 sites — 13 return rich structured data including prices,
product info, and page state not visible in the DOM.

32c035c543 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".
