mckero 5dc7ce6a22 feat(cw): port Morse Expert 1.15 CW decoder engine (feature:cw compiles) ...

Full port of the CW/Morse decoder from Morse Expert 1.15
(com.ve3nea.morse_expert), preserving obfuscated class names and logic.
Ads (gms.ads), billing (BillingClient), and library code were removed per
user; SettingsActivity deferred to Compose integration.

Ported modules:
- pas.*: decoder engine interface + JNI (libnativedecoderjni.so, armeabi-v7a)
- k3.*: FFT library (pseudo-enum q rewritten from smali; sun.misc stubs
  for Unsafe/Cleaner since Android lacks them; FFT path uses float[] branch)
- i3.*, g3.*, j3.*, s.*, d1.AbstractC1518b: DSP/sin-cos tables (long[] tables
  f/f11589g restored from smali)
- H2.a/b: audio capture + decode control core (jadx catch-block illusions
  cleaned per smali; recording try/catch restored around write block)
- J2.a/b: waterfall OpenGL renderer + palette (r10 = anchor color per smali)
- E2.g: waterfall touch frequency picker (height = ScaleView per smali)
- B0.b/B.RunnableC0001b: status-bar + decoded-text UI runnables (real
  constructors recovered from smali)
- MainActivity → controller class (Activity injected; immersive status bar
  inlined); C1646n trimmed to view holder; D.n keeps waterfall texture case
- F2.a: text selection menu (Save/Share)

Verified: :feature:cw:compileDebugJavaWithJavac BUILD SUCCESSFUL.
