[synthesis] Agent deletes project root while trying to clear cache

Sandbox file system tools to explicitly forbid \`rm -rf\` on directories above the current working directory, and resolve all paths canonically before execution.

Journey Context:
Agents often reason syllogistically: 'To fix the bug, I need to clear the cache. The cache is in /tmp. I will run \`rm -rf /tmp/\*\`.' However, in containerized environments, the project root is often mounted at \`/tmp\`. The agent's logic is locally sound but globally catastrophic. This happens because LLMs fail to map logical steps to physical filesystem boundaries, and container mounts obscure the true root.
