Add KYB compliance verification crew using Strale

[petterlindstrom79]

Adds a KYB (Know Your Business) compliance verification crew that uses
crewai-strale for company
data lookup, VAT validation, and AML screening.

What it does

Three agents work sequentially:

1. Company Data Researcher — queries official registries (27 countries) + validates VAT via VIES
2. Compliance Screening Analyst — screens sanctions (OFAC/EU/UN/UK), PEP databases, adverse media
3. KYB Report Writer — synthesizes into a structured report with risk assessment

Why this is useful

KYB/AML verification is a common requirement for agent pipelines in fintech,
compliance, and B2B onboarding. No existing crew in this repo covers this
use case. The Strale integration provides 250+ quality-scored data capabilities
via a single crewai-strale package.
