Version bump for layout table, stack overflow, and noise filter fixes
contributed by @devnen. Also fixes cargo fmt issues that caused CI lint
failure on the merge commit.

Two related fixes for content being stripped by the noise filter:
1. Remove <form> from unconditional noise tags. ASP.NET and similar
frameworks wrap entire pages in a <form> tag — these are not input
forms. Forms with >500 chars of text are now treated as content
wrappers, not noise.
2. Add safety valve for class/ID noise matching. When malformed HTML
leaves a noise container unclosed (e.g., <div class="header"> missing
its </div>), the HTML5 parser makes all subsequent siblings into
children of that container. A header/nav/footer with >5000 chars of
text is almost certainly a broken wrapper absorbing real content —
exempt it from noise filtering.
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).
Sites like Drudge Report use <table> for page layout, not data. Each cell
contains extensive block-level content (divs, hrs, paragraphs, links).
Previously, table_to_md() called inline_text() on every cell, collapsing
all whitespace and flattening block elements into a single unreadable line.
Changes:
- Add cell_has_block_content() heuristic: scans for block-level descendants
(p, div, hr, ul, ol, h1-h6, etc.) to distinguish layout vs data tables
- Layout tables render each cell as a standalone section separated by blank
lines, using children_to_md() to preserve block structure
- Data tables (no block elements in cells) keep existing markdown table format
- Bold/italic tags containing block elements are treated as containers
instead of wrapping in **/**/* (fixes Drudge's <b><font>...</font></b>
column wrappers that contain the entire column content)
- Add tests for layout tables with paragraphs and with links
Research results saved to ~/.webclaw/research/ (report.md + full.json).
MCP returns file paths + findings instead of the full report, preventing
"exceeds maximum allowed tokens" errors in Claude/Cursor.
Same query returns cached result instantly without spending credits.

- --research "query": deep research via cloud API, saves JSON file with
report + sources + findings, prints report to stdout
- --deep: longer, more thorough research mode
- MCP extract/summarize: cloud fallback when no local LLM available
- MCP research: returns structured JSON instead of raw text
- Bump to v0.3.7

__NEXT_DATA__, SvelteKit, and JSON-LD now appear as a
## Structured Data section in -f markdown and -f llm output.
Works with --only-main-content and all extraction flags.

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.

- Extract structured JSON from SvelteKit kit.start() data arrays
- Convert JS object literals (unquoted keys) to valid JSON
- Data appears in structured_data field (machine-readable)
- License changed from MIT to AGPL-3.0
- Bump to v0.3.4

Migrated webclaw-fetch from webclaw-tls (patched rustls/h2/hyper/reqwest)
to wreq by @0x676e67. wreq uses BoringSSL for TLS and the http2 crate
for HTTP/2 fingerprinting — battle-tested with 60+ browser profiles.
This removes all 5 [patch.crates-io] entries that consumers previously
needed. Browser profiles (Chrome 145, Firefox 135, Safari 18, Edge 145)
are now built directly on wreq's Emulation API with correct TLS options,
HTTP/2 SETTINGS ordering, pseudo-header order, and header wire order.
84% pass rate across 1000 real sites. 384 unit tests green.

- --cookie-file reads Chrome extension format ([{name, value, domain, ...}])
- Works with EditThisCookie, Cookie-Editor, and similar browser extensions
- Merges with --cookie when both provided
- MCP scrape tool now accepts cookies parameter
- Closes#7

When a fetch returns a challenge page (small HTML with Akamai markers),
automatically visit the homepage first to collect _abck/bm_sz cookies,
then retry the original URL. This bypasses Akamai's cookie-based gate
on subpages without needing JS execution.

sensor marker on responses under 15KB.

Response.headers() now returns &http::HeaderMap instead of
&HashMap<String, String>. Updated FetchResult, is_pdf_content_type,
is_document_content_type, is_bot_protected, and all related tests.

Document extraction:
- DOCX: auto-detected, outputs markdown with headings (via zip + quick-xml)
- XLSX/XLS: markdown tables with multi-sheet support (via calamine)
- CSV: quoted field handling, markdown table output
- All auto-detected by Content-Type header or URL extension
New features:
- -f html output format (sanitized HTML)
- Multi-URL watch: --urls-file + --watch monitors all URLs in parallel
- Batch + LLM: --extract-prompt/--extract-json works with multiple URLs
- Mixed batch: HTML pages + DOCX + XLSX + CSV in one command

--only-main-content, --include, and --exclude were ignored in batch
mode because run_batch used default ExtractionOptions. Added
fetch_and_extract_batch_with_options to pass CLI options through.
Closes#3

Watch mode:
- --watch polls a URL at --watch-interval (default 5min)
- Reports diffs to stdout when content changes
- --on-change runs a command with diff JSON on stdin
- Ctrl+C stops cleanly
Webhooks:
- --webhook POSTs JSON on crawl/batch complete and watch changes
- Auto-detects Discord and Slack URLs, formats as embeds/blocks
- Also available via WEBCLAW_WEBHOOK_URL env var
- Non-blocking, errors logged to stderr

Adds --output-dir flag for CLI. Each extracted page gets its own file
with filename derived from the URL path. Works with single URL, crawl,
and batch modes. CSV input supports custom filenames (url,filename).
Root URLs use hostname/index.ext to avoid collisions in batch mode.
Subdirectories created automatically from URL path structure.

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".

Crawl:
- Real-time progress on stderr as pages complete
- --crawl-state saves progress on Ctrl+C, resumes from saved state
- Visited set + remaining frontier persisted for accurate resume
MCP server:
- Reads WEBCLAW_PROXY and WEBCLAW_PROXY_FILE env vars
- Falls back to proxies.txt in CWD (existing behavior)

Reddit blocks TLS-fingerprinted clients on their .json API but
accepts standard requests with a browser User-Agent. Switch to
a non-impersonated primp client for the Reddit fallback path.

Critical:
- MCP server identifies as "webclaw-mcp" instead of "rmcp"
- Research tool poll loop capped at 200 iterations (~10 min)
CLI:
- Non-zero exit codes on errors
- Text format strips markdown table syntax
MCP server:
- URL validation on all tools
- 60s cloud API timeout, 30s local fetch timeout
- Diff cloud fallback computes actual diff
- Batch capped at 100 URLs, crawl at 500 pages
- Graceful startup failure instead of panic
