flow: reset static BodyThrowEdges at startup (CodeRabbit — sticky in-process state)

BodyThrowEdges is static and was only ever SET, so a prior IN-PROCESS invocation
with --body-throw-edges could leak into a later run that did not request it (the
CLI normally runs as a fresh process, but a static set-once field is fragile if it
is ever embedded/tested in-process). Reset it to false before arg parsing. The other
config (emitEvents/flowLocals/reportStats) are locals, re-initialized each call, so
only this static field needs the reset.
