[synthesis] Agent changes working directory in step 1 causing relative paths to fail silently in step 7

Never rely on relative paths or cd in agent tool execution; always resolve and pass absolute paths, or execute shell commands in subshells to isolate state.

Journey Context:
Agents execute tools sequentially. Step 1 runs cd /tmp && build. Step 7 runs rm -r ./build assuming the original directory. Because the agent's mental model is stateless but the shell is stateful, it deletes the wrong directory. The silent failure compounds: it creates files in the wrong place, then deploys from the old place, resulting in stale or missing deployments. The fix is treating every tool call as a side-effect-free function by enforcing absolute paths and subshell isolation, synthesizing functional programming principles with stateful OS process management.
