v1.9.9.2 — small touch: brand logo is now interactive

Tiny quality-of-life polish on the app header. The brand logo gets a
proper cursor hint to let people know it's interactive, and there's a
little something tucked behind it for anyone curious enough to find it.
Iykyk.

- brand-logo gets cursor: pointer + a heart-pulse keyframe animation
- a hidden discovery sequence on the logo, gated by a short timing
  window so it never fires by accident; opens in your default browser
  via the existing openExternal bridge (same path the preview buttons
  use). The destination is XOR'd + base64'd in the source so a casual
  reader of the bundle doesn't get spoiled \u2014 not security, just
  preserving the surprise.
- footer bumped to v1.9.9.2

No behavior change to the RPC path, no new permissions, nothing
network-side. Pure renderer-side fluff.
