+// These assert EXIT CODES (help/usage handling), not performance — so they must
+// not be timing-sensitive. `run()` lazily imports each command's (sometimes heavy:
+// migrate-ts, codegen) module on first dispatch; on a cold/contended CI runner that
+// first cold-start import can exceed bun's default 5s test timeout, flaking the
+// suite even though every call returns instantly once warm (~115ms for the whole
+// file locally). A generous explicit timeout eliminates that flake while still
+// failing loudly on a genuine hang or wrong exit code.
