SDK PACKAGE LAYOUT

Three consequences:

1. The directory name is not the namespace name. extendedBookings lives in auto_sdk_bookings_extended-bookings. Don’t derive one from the other; the SDK lookup maps them.
2. The entity is not always in index.typings.d.mts. Order, Refund, Service live in the hashed *.universal-*.d.mts when the package has one. The hash changes between versions, so glob for it, never hard-code it, and fall back to index.typings.d.mts when no universal file exists.
3. Never cat or plain-grep the barrel’s export block. These files end with a single several-hundred-KB export { … as a, … as b } line, so grep -n "queryServices" index.d.mts prints that whole line. Anchor to the declarations instead — grep -oE "^declare (const|function) [a-zA-Z]+" — or pipe any barrel grep through cut -c1-200.
