fix(loader): packageDist NO-SOURCE on clean + relax Minecraft filter

build.gradle
  - Rewrite packageDist: drop the Copy task type and use a plain
    task with `copy { from src; into ... }` inside doLast. The
    Copy task snapshots its source set at configuration time, so
    a first `./gradlew clean dll` saw the source path before
    buildNative produced OpenZenLoader.exe and ended the task as
    NO-SOURCE. Doing the copy in doLast defers source resolution
    to after buildNative, which is when the EXE actually exists.
  - Bail with a clear GradleException if the EXE is still missing
    after buildNative instead of silently leaving build/dist
    empty, and log the packaged size on success.

native/loader/src/MainWindow.cpp
  - Loosen the in-game window filter to: title startsWith
    "Minecraft" OR window class equals "GLFW30" (case-insensitive).
    GLFW30 is the LWJGL3 window class Minecraft uses before the
    title is set, so this catches the early-startup window too.
    Drop the "Launcher" blacklist - launchers are no longer
    matched by either branch.
