WhatsApp rejects handshakes advertising Baileys' baked-in stale protocol
version with a 405 close, so the plugin cycled starting->disconnected and
never issued a QR. connect() now fetches the current WA Web version per
socket build. /status also exposes lastError so this failure mode is
diagnosable from the documented troubleshooting surface.
The published bundled.js also failed to load entirely ("Dynamic require
of 'crypto' is not supported"): plugin bundles are ESM but Baileys is
CJS. bundlePluginEntry now injects the same createRequire banner as
dist/bin.js.
Verified end-to-end against an isolated fn serve: bundled.js loads,
status reaches awaiting-qr, /qr serves a scannable QR data URL,
/pair-code validates input, /logout clears auth state.
