[FEATURE] skill metadata - limit tool visibility

Preflight Checklist

• [x] I have searched existing requests and this feature hasn't been requested yet
• [x] This is a single feature request (not multiple features)

Problem Statement

Currently when a user invokes a skill, the workflow from the skill.might trigger tools configured outside of the skill.
In some cases this produces an undesirable result. E.g: the user configured manually ab mcp server and now it has contradicting context

Proposed Solution

Add metadata to the skill with which tools are available/visible to the skill. The current allowed-tools is for auto approval of tools without asking permission.
The use case above is different. Want to be able to specify visibility and not even be asked. By default available tools must be tools self contained in the plugin with the option to extend that list.
