Zero-Network Agent Guard & Rule Playground

Evaluate coding-agent diffs against Brevio’s deterministic rule engine (`R1.1`–`R19.4`: 12 scanned line rules, 9 AST surface rules, and 10 pre-PR flight gates out of 123 rules) in real time. Catches self-mocking tests (R6.1), arbitrary sleep waits (R6.3), hardcoded credentials (R13.1), unsafe code sinks (R2.8), and TypeScript slop (R9.1–R9.3) before PR merge. Includes instant 1-click deterministic auto-fixes and compile to .brevio/guards.json.
