Agents: preserve plugin tool metadata through wrappers

Keep plugin-origin metadata attached when agent tool definitions are cloned or
wrapped by schema adapters, before-tool hooks, abort handlers, and Gemini tool
sanitization.

Without this, an exact-name external plugin such as `web_search` can lose its
plugin marker during normalization and be mistaken for a trusted built-in when
MEDIA URLs are filtered.

Add regression coverage proving wrapped exact-name plugin tools remain
untrusted for local-path media passthrough.
