CompileBuildOptions.jitPolicy

The JIT policy the executable starts with (see Bun.unsafe.setJITPolicy). 1 is the normal policy. A value > 1 multiplies JavaScriptCore's tier-up thresholds so code that only runs during startup stays in the interpreter longer; the app should call Bun.unsafe.setJITPolicy(1) once it is interactive.

Equivalent CLI flag: --compile-jit-policy <n>
