Daily-index metadata browse (any form type)
Browse SEC EDGAR daily-index master.idx parsed metadata. Returns all filings on a given date matching the optional form code and CIK filters. For B2 v1 high-value forms (Form 4/4-A, 8-K/A, SC 13D/G/A) the rows reflect deep-parse status (parse_attempted, parse_status). For PASSTHROUGH forms (10-K, 6-K, S-1, etc.) the rows carry master-idx metadata only - use form-specific endpoints for deep data. Returns 503 when the master-idx blob is missing for the requested date.
