Package both launcher and console into dist\ (parity)

- Launcher/build.bat now outputs to dist\TeslaLauncher\ (was TeslaLauncher\ at the
  Launcher root) and produces dist\TeslaLauncher-podpkg.zip, matching Console\dist\.
- Both build scripts now zip the package themselves (Compress-Archive) instead of
  leaving it as a manual step: Console/build-package.bat -> dist\TeslaConsole-pkg.zip.
- Launcher/.gitignore: ignore /dist/ (drop the obsolete /TeslaLauncher/ + staging
  entries); Console already ignores /dist/.
- READMEs updated to point at dist\.
