Module action 

Semantic build-action IR.

The planner emits these toolchain-independent action specs; the crate::lower() layer turns them into concrete command argv for a specific crate::Dialect. Nothing here names a compiler flag: the IR records intent (optimization level, debug info, defines, include directories, the source language) and each dialect spells it (-O2 vs /O2, -c vs /c, …). A new dialect is added in crate::lower() without this IR changing.
