[synthesis] Shell tool changes working directory, breaking subsequent relative path references in agent memory

Always use absolute paths for file operations, or explicitly reset the working directory \(cd - or absolute cd\) after any command that mutates it.

Journey Context:
Agents often execute shell commands sequentially. If step 1 is 'cd /var/log && grep ERROR sys.log', the shell's CWD is now /var/log. Step 2 might be 'rm ./temp/app\_cache', which the agent intended relative to the original CWD, but now resolves to /var/log/temp/app\_cache. If the agent creates a new directory there, it diverges from the actual application state. The synthesis is between POSIX process state inheritance and stateless agent tool design: agents treat each tool call as stateless, but the underlying OS maintains stateful side effects that silently corrupt path resolution.
