/**
 * If the legacy account's `_keychain.claudeAiOauth` access token is expired
 * (or about to expire), call the Anthropic OAuth refresh endpoint and rewrite
 * the snapshot in-place. Returns true when a refresh actually happened, false
 * otherwise (no _keychain, no refresh_token, fresh tokens, or refresh failed).
 *
 * Called internally by `ensureProfileForAccount` before the sync
 * `importProfileFromAccount` flow, so the snapshot landing in the Keychain
 * / per-profile JSON is fresh by construction. Without this pre-step, profiles
 * dormant for hours/days would carry expired access tokens straight to claude,
 * which then 401s instead of auto-refreshing (it doesn't auto-refresh in
 * --print mode against a non-default config dir).
 *
 * Failure is silent: we log nothing, return false, and let the caller fall
 * through to its existing "needsLogin" handling.
