/**
 * Operator-facing strings for the pi-teammate-models CLI.
 *
 * English is the reference map; every other locale must carry exactly the same
 * key set (checked by `checkCatalogCompleteness`). The raw catalogs are merged
 * into the central TUI catalogs in src/tui/locale.ts so the extension and the
 * CLI can never drift apart, while the typed translator below keeps the CLI
 * independent of the interactive locale lifecycle (a CLI invocation has no
 * Settings event stream, so its locale comes from --locale alone).
