Add OSINT dossier builder (activsint patterns) for facility operators

[stuckvgn]

Build a facility operator dossier builder using patterns from the activsint starred repo.

Purpose

Investigators need to quickly build profiles of facility operators (owners, corporate entities, parent companies) to:

• Identify repeat offenders operating under different LLCs
• Map corporate relationships between facilities
• Surface public records (court filings, regulatory actions, business registrations)

Scope

• src/regulatory/dossier.py — dossier builder module
• Input: facility name, license number, or owner name
• Outputs: structured dossier with corporate relationships, known addresses, associated facilities
• Sources: public records only (USDA license database, state business registries, court records)
• Store dossiers encrypted in the evidence volume

Security

• Dossier data is investigation-sensitive — store in evidence/ not data/
• Chain of custody log on every dossier operation
• Never query sources that log requester identity
