## Builds the Logger-based test script-error capture lazily.
##
## Logger exists only on newer Godot versions. The capture implementation lives
## under a `.gdignore`d folder and is compiled from source only after the runner
## verifies the Logger API is present, so older editor scans do not parse an
## `extends Logger` file and emit red startup errors.
