Minor Bug/Inconvenience: Propagate Permission Across Parallel Tool Calls.

Noticed that if parallel tool calls happen and there is no permission for those, yet, even though you give permission once, you will still be asked N times.

Example:

• Asked it to read 3 docs.
• It makes 3 fetches in parallel.
• I allow performing fetch on everything on docs.anthropic.com domain.
• It still asks me 3 times to do the thing.
