Linux install status

Linux packages are planned for v1.0. Until .deb, .rpm, or another packaged install path is available, Linux users can build icuvisor from source if they are comfortable with Go tooling.

Current recommendation

• Follow the repository build instructions on GitHub: Build from source.
• Store API keys with libsecret/Secret Service where available. On systems without libsecret, use process environment only for deliberate headless or emergency fallback.
• Use the config file reference for JSON config fields and default config paths, or the CLI environment variable reference when configuring icuvisor through process environment.

The future Linux packages will keep the same local-first security model: the intervals.icu API key belongs in the OS keychain or setup flow, not in MCP client JSON.
