fix: async Warden PAGE_A/PAGE_B checks to prevent main-loop stalls

Browse source 
Move 5-second brute-force HMAC-SHA1 code pattern searches to a
background thread via std::async. The main loop now detects PAGE_A/B
checks, launches the response builder async, and drains the result
in update() — encrypting and sending on the main thread to keep
wardenCrypto_ RC4 state thread-safe.

Also adds Turtle WoW PE binary support (isTurtle flag, dedicated exe
search, runtime patches), searchCodePattern with result caching,
writeLE32 public API, and Warden scan entry verification.
