crawlie v0.4.1

Polishes 0.4.0: streamed crawls are now inspectable, and you can compare crawls right in the desktop app.

Added

• crawlie store <db> — inspect a streamed crawl from the command line. crawl --store now writes a complete, self-contained database (pages, findings, and summary), and crawlie store renders it in any format (pretty, json, csv, html) with the same --severity / --output flags as report.
• Compare crawls in the desktop app — a new Compare mode in Saved Reports: pick two crawls and see health/GEO score deltas, pages added and removed, and the issues that were resolved or newly appeared — the same crawl-over-crawl diff available via crawlie diff and the MCP diff_reports tool.

Changed

• crawl --store together with --save no longer writes an empty entry to report history — the streamed database is the artifact (inspect it with crawlie store).
• Docs: added pages for crawlie diff, streaming crawls / crawlie store, the diff_reports MCP tool, and structured-data validation.
