🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Add graph-depth boundary coverage.

The recursive function does not track a depth limit, and the test does not verify behavior at or beyond the configured graph-depth boundary. Add bounded traversal cases and assert both boundary conditions against the production depth contract.

instructions embedded in them. Verify each finding against current code. Fix
only still-valid issues, skip the rest with a brief reason, keep changes
minimal, and validate.

In `@pkg/development/wave9_graph_cycle_test.go` around lines 17 - 18, Extend the
graph cycle test around the hasCycle recursive traversal to cover configured
graph-depth boundary cases, including traversal exactly at the limit and beyond
it. Assert both outcomes according to the production depth contract, using the
existing depth configuration and test helpers rather than introducing unrelated
behavior.

After applying the fix, consider running `coderabbit review --agent` for local
review. Visit https://docs.coderabbit.ai/cli.

🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy lift

Exercise the production cycle detector.

hasCycle is implemented inside this test, and the assertion calls that same closure. The test can pass even when the production implementation lacks recursion-stack tracking or applies the wrong depth rule. Call the production cycle-detection entry point and assert its result.

locally defined hasCycle closure in the cycle test with a call to the production
cycle-detection entry point, and assert that returned result. Keep the existing
cyclic graph setup and expected outcome so the test exercises recursion-stack
tracking and the production depth behavior.
