Subject: [PATCH] feat(tools): fall back to main-executable when framework is
 absent

build_patched_ipa.sh assumed the hook target lived at
`Payload/<name>.app/Frameworks/<FRAMEWORK>.framework/<FRAMEWORK>`,
which works for Unity-style consumers (KiouEditor, KiouKifExporter)
whose hook sites are in UnityFramework but breaks for pure Swift /
Objective-C apps whose hook sites live directly in the CFBundle
executable.

When --framework points at a Mach-O that doesn't exist under
Frameworks/ but does exist at the .app root, treat it as the main
executable instead. Existing Unity consumers see no behaviour change
(their framework path exists, so the fallback branch is never taken).

PiyoShot (targeting PiyoShogi.app/PiyoShogi) is the first consumer of
the new path.
