Dynamic mode

The application enables the loader before constructing its interface:

aura::ui::Loader::global().enableFromEnvironment(); // AURA_DIR

Use AURA_DIR to select source files. Without a value, the application uses its compiled UI:

AURA_DIR=$PWD/ui ./my-app
AURA_DIR= ./my-app

• Loading: before every construction, the loader checks the modification times of all *.aura files in the directory and its subdirectories and reloads all files when anything changes. A change becomes visible the next time the dialog opens.
• Identical behavior: the interpreter (libs/aura-ui/src/builder/) follows the generator's rules step by step: property order, deferred properties, pressed groups, bindings, and rebuilding with anchors and guards.
• Errors: if the dialog is missing from the directory or a file contains an error, a warning is written to the log (W [aura]) and the compiled version appears. Partially constructed nodes are removed first. Because this happens without interrupting the application, watch the log while developing.
• Versions: if the file and compiled application do not match (for example, a new argument), the loader reports “no value for the argument” and uses the compiled version.
• Availability: development builds only.
• Enabling: aura::ui::Loader::global().enableFromEnvironment("AURA_DIR") (default name AURA_DIR): takes the directory from the environment and writes errors and notices to the log.
• Without the application: tools/aura-view displays dialogs and screens independently of the application's flow, including live updates while typing in VS Code (aura-view.md). It supplies placeholders for dialog arguments ("test-<name>", 0, false; record lists with one entry).
