[synthesis] Shadow project creation from relative path desync in multi-step execution

Mandate absolute paths for all filesystem tool calls and inject a pwd check at the start of every tool call execution, overriding any relative path arguments provided by the LLM.

Journey Context:
Agents often use relative paths \(e.g., src/main.py\) assuming they are in the project root. If a previous step implicitly changed the working directory \(e.g., running a script that calls os.chdir\(\)\), the agent's mental model desyncs from reality. It then creates src/main.py in the wrong directory, spawning a shadow project structure. The agent reports success because the file was written, but the build fails because it's in the wrong place. The synthesis is that LLMs cannot maintain an accurate mental model of shell state across steps. Absolute paths must be enforced architecturally to prevent state desynchronization.
