Commit Message

build: force -O0 project-wide under UBSan

UBSan above -O0 is superlinear in the optimiser here: one score_plugin_avnd TU
measured >420 s and 5.7 GB at -O1 against ~14 s at -O0, with identical sanitizer
coverage. The existing rule covered that one plug-in, so every other target still
paid it.

This is a workaround for a toolchain defect rather than something worth keeping,
so it is opt-out: -DSCORE_UBSAN_KEEP_OPTIMISATION=1 builds a UBSan tree at the
build type's own optimisation level, which is how to check whether the compiler
still needs this. The block should be deleted once it does not.

ASan is deliberately not included. It is unaffected by this defect, and its
memory cost at -O2 is a function of build parallelism rather than optimisation
level.
