lingxia-app-context

Shared app/product context primitives for LingXia workspace crates.

What it owns

• Parsing and validating app.json
• Global process-level app config access
• Shared derived paths under the app state directory
• Panel configuration structs used by shell/product crates

Key APIs

• AppConfig::parse_and_validate(...)
• set_app_config(...) -> Result<(), AppContextError>
• app_config()
• product_name(), product_version(), lingxia_id()
• app_state_dir(...), app_state_file(...)

Notes

This crate is intentionally small and dependency-light so higher-level crates can share app metadata without depending on lxapp runtime code.
