* fix: add timeout to fetchLatestBaileysVersion to prevent hanging connections

AbortController with 5s default timeout prevents indefinite blocking
when GitHub is unreachable (DNS failure, network issues). Falls back
to bundled version via existing catch block. Ref: Baileys#2385.


* fix: move clearTimeout to finally block in fetchLatestBaileysVersion

Ensures timer cleanup on both success and fetch rejection paths,
preventing dangling timers when DNS/network fails before abort fires.
