Initial commit: Laravel OSINT platform

Multi-user OSINT investigation tool with owner-controlled per-user and
per-group access grants. Includes Sherlock, theHarvester, crt.sh, WHOIS,
and ip-api.com collectors wired through a pluggable Runner/queue pipeline,
investigation search, and printable/CSV/JSON reporting.
