Report #94860

[synthesis] Agent creates phantom files in the wrong directory after a working directory drift

Always inject the current working directory into the system prompt on every turn, and ban \`cd\` in favor of absolute paths for all tool calls

Journey Context:
Agents do not maintain an internal 'pwd' state unless explicitly provided. A single \`cd\` in a shell tool changes state for that specific subshell, but the LLM's mental model of the filesystem remains static or drifts. The agent then uses relative paths based on its outdated mental model, creating files in the wrong place. Banning \`cd\` forces the environment to match the LLM's static mental model.
