#2188: Spyder commandlet starts spyder in foreground

[vivu001]

This PR fixes #2188

Related PR #1954

Implemented changes:

• Spyder now uses the IDE launch path and starts in the background instead of blocking the terminal.
• SPYDER_CONFIG_DIR is set to an IDEasy-managed config directory under conf/spyder.
• Spyder is now modeled as an IDE-style commandlet rather than a plain pip tool.

---

Testing instructions

1. Run ./build-local-dev.sh to build the native image.
2. Launch Spyder with:

ide spyder

Expected behavior:

Spyder opens its GUI and the terminal returns to a new prompt immediately so you can keep using it.
