Normalize dist layout and disable npm rebuild in release workflow

[cita-777]

Motivation

• Ensure the downloaded build artifact is placed and normalized into a consistent dist/desktop layout across Windows, Linux and macOS runners.
• Avoid downloading and extracting AppImage tooling when not required by simplifying layout handling.
• Make desktop packaging more deterministic and faster by disabling automatic npm rebuild during package:desktop runs.

Description

• Changed the artifact download path from . to dist so the downloaded artifact is placed under dist/.
• Added a Windows-specific normalization step (PowerShell) that moves or copies top-level desktop, web, and server folders into dist/ and validates that dist/desktop/main.js exists.
• Replaced the previous Linux/macOS normalization that fetched AppImage tools with a simpler shell step that flattens dist/dist/ or moves top-level folders into dist/ and verifies dist/desktop/main.js.
• Updated desktop package steps on Windows, Linux and macOS to run npm run package:desktop -- --config.npmRebuild=false and removed the AppImage tools env variable and prefetch logic.

Testing

• No automated tests were executed as part of this change.

🐰 A path correction, so precise,
From dot to dist, a swift device,
The workflow gleams with clarity bright,
Our artifacts download just right! ✨

🚥 Pre-merge checks | ✅ 2 | ❌ 1

❌ Failed checks (1 inconclusive)

Check name	Status	Explanation	Resolution
Title check	❓ Inconclusive	The title mentions 'normalize dist layout' which aligns with the main objective of ensuring consistent dist structure, and references 'disable npm rebuild' which is a key change. However, the raw_summary only documents the artifact download path change, not the full scope of changes described in PR objectives.	Clarify whether the title should reflect only the documented download path change or the full scope including npm rebuild and platform-specific normalization steps.
