Snapshot 95 demo-tenant parsers (incl. stormshield) + un-ignore parsers/

The original upstream gitignores parsers/* on the assumption that each tenant
has its own set. This fork commits a working snapshot so the Parser Test Runner
and Parser Coverage features are usable out of the box.

Stormshield parser exercises the new SDL key=value scanner, pattern references,
and JS-style unquoted format keys added to backend/routers/quality.py.
