Initial release infrastructure Add README, LICENSE, and platform install scripts (install.sh for macOS/Linux, install.ps1 for Windows). The install scripts fetch the latest release binaries from this repo. Replaces the placeholder README file. Source code is maintained in a separate private repository; only built artifacts and the website are published here. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
