IPO signals now include SEC S-1 and F-1 filings

IPO market signals now use official SEC EDGAR filings in addition to web sources.

What changed

• Discover S-1 and F-1 registration filings, including amended filings.
• Normalize issuer names, filing dates, accession numbers, and source links from SEC data.
• Use sources: ["edgar"] for filing-only subscriptions, or combine web and edgar for broader discovery.
• Avoid cross-source duplicates when the same IPO event appears in both web and filing evidence.

Customer action

Existing subscriptions continue to use their configured sources. Add the edgar source when official filing evidence should be included, or use only edgar when a filing is required.
