basecamp: Deprecate manifest

[haussmann]

Recommendation to deprecate Basecamp 2, because:

• Basecamp switched to version 4 at least since September 2022 (source)
• Basecamp (4) switched to a portable web app based solution for Windows (source)
• Download links, checkver and autoupdate are no longer working

Relates to #16379

• Use conventional PR title
• I have read the Contributing Guide

Walkthrough

A new top-level key named ## was added to deprecated/basecamp.json, containing an array of two deprecation messages about Basecamp: one noting Basecamp 3 is no longer available as a stand‑alone Windows app and another stating Basecamp 3 and 4 moved to a portable web app model. No other fields or logic were changed.

🐰 I scribble notes beneath the moonlight,
Two little lines to mark the flight,
Windows doors closed, the web takes flight,
A tiny carrot of truth tonight. ✨

⚠️ Potential issue | 🔴 Critical

Critical: Deprecation message incorrectly identifies the manifest version.

The deprecation message states "Basecamp 2 is no longer available" but this manifest is clearly for Basecamp 3, not Basecamp 2. Evidence:

• URLs reference basecamp3-2.4.3-full.nupkg (line 15)
• Executable name is Basecamp 3.exe (line 22)
• All checkver and autoupdate patterns match basecamp3 (lines 28, 34)

The version 2.4.3 is the version number of Basecamp 3, not Basecamp 2.

Apply this diff to correct the deprecation message:

     "##": [
-        "Deprecated 2025-12-17: Basecamp 2 is no longer available for windows.",
+        "Deprecated 2025-12-17: Basecamp 3 is no longer available for Windows.",
         "Basecamp 3 and 4 switched to a portable web app model"
     ],

Note: This also capitalizes "Windows" for consistency.

🤖 Prompt for AI Agents

In deprecated/basecamp.json around lines 2 to 5, the deprecation message
incorrectly refers to "Basecamp 2" and uses lowercase "windows"; update the
deprecation text to reference "Basecamp 3" (e.g., "Deprecated 2025-12-17:
Basecamp 3 is no longer available for Windows.") and ensure "Windows" is
capitalized for consistency with other manifests.
