Bring clients/cli/src/cliOAuth.ts from 75% to ≥90% on all four coverage
dimensions (now 100/96.42/100/100) by exercising the previously-untested
interactive step-up and auth-recovery paths:
- confirmStepUpFromStdin (the default stdin confirmer): drive it via the
default `confirmStepUp` parameter of handleCliAuthRecoveryRequired with
node:readline/promises mocked — covers the y / "yes" (trimmed,
case-insensitive) accept paths and the n decline path (which throws).
- connectInspectorWithOAuth's AuthRecoveryRequiredError branch: both the
storage-already-satisfies resume and the interactive-recovery sub-branches,
plus the isUnauthorizedError branch (with a rejecting disconnect to hit the
`.catch(() => {})` guard), the non-OAuth-capable-config rethrow, and the
non-OAuth-error rethrow.
Part of #1610 — v2/main mid-session-auth code below the per-file coverage
gate that v2/main's CI does not run but the Wave-1 rollup (#1550) does.
