funman300 ab803c07af fix(android): remove unused JValue import and fix match arm types
Two cfg(android) issues hidden from Linux CI:
- android_clipboard.rs: JValue was imported but never used (JValueOwned
  covers all call sites). Removed to satisfy -D unused-imports.
- stats_plugin.rs: both arms of the clipboard match now return () via
  explicit block+semicolon, resolving the type mismatch that pinged-pong
  between runs due to bidirectional match-arm type inference.
