/**
 * agent-settings-page.tsx resolveTabKey unit tests: the settings page's `?tab=` deep link
 * narrows an untrusted query value against the live TABS keys — a known key passes through,
 * anything else (absent, empty, unknown, wrong casing) falls back to the default — pinned so
 * the validation stays dynamic and newly added tabs deep-link without a hardcoded key list.
