fix: quote test glob so Node expands it, drop --experimental-strip-types
Shell glob ** doesn't match files in the immediate directory in sh,
only subdirectories. Quoting lets Node's test runner handle the glob
which correctly matches test/*.test.ts and test/**/*.test.ts.
Node 24 strips types natively so the flag is unnecessary.
