Brand rename propagation: 'Cat Cafe' remnants across desktop installer, splash, launcher, docs

[mindfn]

Problem

The brand rename from "Cat Cafe" to "Clowder AI" was partially applied — desktop/package.json productName and main.js window titles were updated, but many user-facing files still reference the old name.

Related: #1104 (exe name mismatch in Inno Setup, a subset of this issue)

What NOT to change

• npm package names (cat-cafe-desktop, @cat-cafe/*) — internal identifiers
• Directory names (.cat-cafe/, cat-cafe-skills/) — runtime paths
• Git remote names and code-level identifiers

Root Cause

Brand rename to "Clowder AI" updated Electron config but not installer scripts, launcher, splash screen, or docs.

Fix PR opened: #1109

Scope: desktop installer, launcher, splash, build scripts, and docs public branding. Internal identifiers such as package names and @cat-cafe imports are intentionally unchanged. Source sanitizer PR: https://github.com/zts212653/cat-cafe/pull/2782
