index: repin reasoning-switch to 1.1.1

[apoapostolov]

Repins reasoning-switch from d7c4c70 (1.0.7) to 9374f674 (v1.1.1 + README in the same commit).

What changed since the pinned ref

• Working source link: the desktop denies target="_blank" window-opens by design (window-open-policy.ts, CVE-2026-70608 hardening); the dialog's external link now goes through ctx.os.openExternal, the audited external-link door.
• Dialog polish: the dialog hugs its content (fitContent) instead of a fixed width; dark-mode-correct native select options; choosing a color tints checkbox, label, and dropdown state; number inputs without spinners.
• Header layout fix: the hint paragraph is its own block; the header row holds title + GitHub icon left of the close button.
• Hint trimmed so it no longer stretches the dialog.
• ESM-parse fix for the loader (ternary without else passed CJS node --check but failed the ESM loader).
