Overview

SERVER-133147 / PR #60622 temporarily converts the tassert(13002310, ...) in IncrementalFeatureRolloutContext::set() (src/mongo/db/ifr_context_decoration.cpp) to an invariant(...) so a hit crashes the process (and hopefully produces a core dump) instead of logging and continuing, to aid the BF-45368 investigation.

Scope of Work

* src/mongo/db/ifr_context_decoration.cpp — revert the invariant(...) back to tassert(13002310, "Refusing to replace an IFRContext whose egress metadata has already been cached", ...) once a useful crash/core dump has been captured (or once the BF-45368 root cause is otherwise understood without one).

Acceptance Criteria

* The diagnostic invariant is reverted back to tassert(13002310, ...).
* This ticket does not attempt to fix BF-45368 itself — only to undo the temporary diagnostic change once it's no longer needed.
