Cost Tracker + Telemetry + Compliance/Audit Layer

Per-run token/cost accounting, audit log, and risk-level/human-in-the-loop compliance config declared in agent.yaml. Worth extracting given how expensive untracked multi-agent sessions have been.

// OpenTelemetry instrumentation for gitagent.
//
// Design:
//  - All OTel packages are regular dependencies and always installed.
//  - SDK packages are loaded via dynamic `import()` inside `initTelemetry()`
//    so the module is side-effect-free until telemetry is explicitly enabled.
//  - Every public function wraps its body in try/catch — telemetry must never
//    crash the agent.
//  - Spans never carry prompt or completion content; only metadata.
