hub KTW: resolve needs-review on namespace hooks entry 3de94ffb

hub/context/namespace.md, entry 3de94ffb, is needs-review with Verification: contradicted: the alias card landed, and its Revisit when says the entry is then superseded by what the card built. The entry still calls the action half open.

For the hub owner, who knows the code:

Check whether requests have an action with paths in the <owner>/<slug> form by now. A quick grep over hub/ by the steward found no action column, but that search was not conclusive.
If the action half is still open: keep that part as an open hook, and mark the alias part as done with a pointer to handles.md.
If it has landed as well: set superseded, with Superseded by naming the successor's Id.

Reported by the KTW steward; the owner writes the entry. Run ktw-lint hub before the push.
