.SYNOPSIS
  Configure, build, install, and run emotiv_lsl in one step.

.DESCRIPTION
  Runs cmake --workflow --preset emotiv (configure + build), then installs the
  self-contained bundle to build/install/ (copies lsl.dll/liblsl.so next to
  the binary), then launches emotiv_lsl. All C++ dependencies (liblsl, hidapi,
  tiny-AES-c) are fetched automatically by CMake on first run.

  If a stale CMakeCache.txt exists from a different generator, it is removed
  automatically before configuring so the build stays consistent cross-platform.

.EXAMPLE
  pwsh ./run.ps1
