feat(wfe-yaml): add deno_core JS/TS executor with sandboxed permissions
Secure JavaScript/TypeScript execution in workflow steps via deno_core,
behind the `deno` feature flag.
Security features:
- Per-step permission system: net host allowlist, filesystem read/write
path restrictions, env var allowlist, subprocess spawn control
- V8 heap limits (64MB default) prevent memory exhaustion
- Execution timeout with V8 isolate termination for sync infinite loops
- Path traversal detection blocks ../ escape attempts
- Dynamic import rejection unless explicitly enabled
Workflow I/O ops:
- inputs() — read workflow data as JSON
- output(key, value) — set step outputs
- log(message) — structured tracing
Architecture:
- JsRuntime runs on dedicated thread (V8 is !Send)
- PermissionChecker enforced on every I/O op via OpState
- DenoStep implements StepBody, integrates with existing compiler
- Step type dispatch: "shell" or "deno" in YAML
34 new tests (12 permission unit, 3 config, 2 runtime, 18 integration).
