Ruben Fiszel 22cce51db5 fix: return null for non-existent step access in flow expressions
Previously, accessing a non-existent step via results.nonexistent would
throw an error. This fix makes both Deno Core and QuickJS return null
instead, enabling patterns like:

- results.nonexistent ?? 'default'
- results.nonexistent?.value ?? 'default'

The fix was applied to:
- js_eval.rs: handle_full_regex fast-path now uses .ok().flatten()
- js_eval_quickjs.rs: fallback path now uses .ok().unwrap_or(null)

Added flow engine test to verify the behavior.
