v0.0.37 — backup toolsets stop appearing where their plugin is not

A single focused fix.

The problem

toolset/updraftplus and toolset/all-in-one-wp-migration appeared in an MCP server's tool picker — and in the set a new server starts with — whether or not the backup plugin was anywhere on the site.

Every other per-plugin toolset already excluded itself. Elementor, Rank Math and LiteSpeed opt out precisely so the default set does not differ per site. These two, added in 0.0.35, did not.

Measured with both backup plugins deactivated:

toolset/updraftplus              declared: True   ← wrong
toolset/all-in-one-wp-migration  declared: True   ← wrong
toolset/elementor                declared: False  ← correct
toolset/litespeed-cache          declared: False  ← correct

Why it matters

A default tool set that changes when a plugin is activated is one a connected MCP client cannot be told about — it caches tools/list and has no way to learn that it moved.

Nothing is lost

The tools themselves were never broken. With the plugin active they still register, are still addable by hand from the picker, and are still listed and runnable through toolset/integrations. They are simply no longer part of what a new server is given by default.

If a server already has one and the plugin is not installed, Reset to Type Defaults clears it.
