The emitter emits psx_rfe_mark_escape() at every rfe — including in
overlay-resident exception-context code — but the dispatch preamble
never provided it, so any rfe-containing overlay failed to LINK
(undefined reference) and ran interpreted forever: the gte_read_ctrl
silent-coverage-blocker class again (11 of Tomba's vault shards hit
it). It mutates shared RFE-pending escape state (interrupts.c), so the
shim forwards unconditionally through OverlayCallbacks; ABI bump to 12
rejects pre-shim caches.
Found live during LOAD_TIME_ZERO E0 bring-up: the user's first pig
load triggered autocapture and the compile died on this link error.
