Mark Roo Code client integration as deprecated (#909)

The Roo Code VS Code extension was discontinued on May 15, 2026 and its
repository archived, with the upstream team pointing users to Cline.
Reflect this in the docs so they stop signaling the client is supported.

- Flag Roo Code as deprecated in the client compatibility table and add a
  warning to the Roo Code section recommending Cline
- Drop the roo-code (and cline) entries from the CLI registration examples
  in favor of codex and antigravity
- Remove Roo Code from the enterprise supported-clients list

Companion to stacklok/toolhive#5415 (part of stacklok/toolhive#5017).

 ### Roo Code and Cline
 
+:::warning[Roo Code is deprecated]
+
+The Roo Code VS Code extension was discontinued on May 15, 2026 and its
+repository archived. ToolHive support for the `roo-code` client is deprecated
+and will be removed in a future release. The Roo Code team recommends migrating
+to [Cline](https://cline.bot/), which ToolHive also supports:
+
+```bash
+thv client register cline
+```
+
+:::
+
 [Roo Code](https://roocode.com/) (previously Roo Cline) and
 [Cline](https://cline.bot/) store their global MCP configuration in their VS
 Code extension settings directory. Both use the same configuration format.
