chore: sync repository to current working state

Brings azcomputerguru/guru-connect up to the authoritative working copy that
had been maintained in the claudetools monorepo: Phase 1 security and
infrastructure (middleware, metrics, utils, token blacklist, deployment
scripts, security audits) plus the native-remote-control integration spec.
Preserves the repo .gitignore, .cargo, and server/static/downloads.
