/**
 * Combines user intent (settings.voiceEnabled) with auth + GB kill-switch.
 * Only the auth half is memoized on authVersion — it's the expensive one
 * (cold getClaudeAIOAuthTokens memoize → sync `security` spawn, ~60ms/call,
 * ~180ms total in profile v5 when token refresh cleared the cache mid-session).
 * GB is a cheap cached-map lookup and stays outside the memo so a mid-session
 * kill-switch flip still takes effect on the next render.
 *
 * authVersion bumps on /login only. Background token refresh leaves it alone
 * (user is still authed), so the auth memo stays correct without re-eval.
