test(client),ci: fuzz frame parsers, VT-x classifier tests, smoke + CI hardening
- proptest-fuzz the untrusted frame parsers (sbx/ai/perm/users/decode_msg) so a hostile relay/peer can never panic a client; fixes a decode_msg timestamp byte-slice that panicked on a non-ASCII stamp (now char-boundary safe) - extract a pure classify_vtx_holders() out of vtx_holders() and unit-test the KVM/QEMU/multipass detection and stoppability rules - headless cross-stack smoke test (smoke-e2e.sh): real relay + two TUI clients in tmux, asserting SRP join, Fernet chat round-trip, and command dispatch - CI: macOS matrix for the Rust client, cargo-audit + pip-audit, gitleaks secret scan, llvm-cov/pytest-cov coverage, and a smoke-test job Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
