Rename make-row to clarify intent in cables module

[oubiwann]

Problem

In underack.cables, the function make-row creates a tuple representing a pub/sub connection:

(defun make-row (publisher subscriber)
  "Pubsub terminology is used here..."
  \`#(,publisher ,subscriber))

The name "row" suggests database/table thinking, but the actual concept is a connection or subscription between modules.

Suggested Fix

Rename to better reflect the domain:

• make-connection
• make-subscription
• make-cable (matching the module name)

Update all call sites accordingly.

Priority

P2 - Naming clarity, can be done alongside other cables work.
