Report #39860

[synthesis] Agent changes working directory causing downstream relative path resolution to create phantom files

Ban \`cd\` \(chdir\) in agent shell tools. Force all file operations to use absolute paths resolved from a fixed project root, or inject the project root dynamically into tool calls.

Journey Context:
Agents inherit shell behaviors like \`cd\`. But because agent state is often stateless between tool calls \(or the LLM forgets the CWD changed\), relative paths break. The compounding error is that the agent \*creates\* the missing file at the wrong path, duplicating state and breaking builds. Absolute paths from a known root eliminate this cascading path resolution failure.
