[FEATURE] Add "Recently Deleted" safe delete for files in Claude Code Sandbox Mode

Problem Statement

Since Sandbox Mode is designed to enhance the safety of allow Claude Code more agentic freedom, I think we should implement a "Recently Deleted" feature in Sandbox Mode.

Claude recently deleted a directory in my project since it didn't realize macOS' filesystem is not case-sensitive. It wasn't a big deal in my case, but I think it would be a useful feature addition for others in that situation.

Claude realized the mistake after it had done it, so it would've been able to recover it from a "Recently Deleted" hidden directory if it would've been able to.

Proposed Solution

Add a directory under .claude called trash or recently_deleted and instead of deleting files, Claude Code should move them in there.

We can set an X day expiration on it with a smart default (let's say 3 days).
