redis/redis's module and networking layer carries the highest structural debt — 5 functions to address first

The riskiest function in redis/redis hasn't been touched in 51 days, but when it is next changed, whoever opens it will face a nesting depth of 13 and a long if-else chain dispatching across more than a dozen distinct server events. That structural weight is sitting silently in five critical-band functions spread across the module system, client lifecycle, cluster slot migration, and blocked-client machinery — none of them are burning right now, but all of them are overdue for refactoring before the next development push.
