unusedGraphInputsSeverity

Configures the Metro compiler plugin to warn, error, or do nothing when it encounters unused graph inputs (graph factory parameters or directly included binding containers that are not used by the graph).

WARN by default.

Note: DiagnosticSeverity.IDE_WARN and DiagnosticSeverity.IDE_ERROR are not supported here because unused-input detection only runs during IR (a CLI-only phase). Attempting to set an IDE-only severity will fail the build with a validation error.
