QuickJS: measure the JS stack budget from the current stack pointer to the thread's base (the nominal size under-budgeted the Android runtime thread: depth-128 recursion hit the limit)
matthargett
committed

QuickJS: nested 8 MiB Android thread + 6 MiB JS stack limit (supersedes the measured-limit approach; emulator-validated depth-128)
