[synthesis] Agent uses relative paths after a previous tool call silently changed the working directory, writing files to a shadow location

Mandate absolute paths for all file operations. Inject a tool at the start of the agent loop that resolves the current working directory, and prepend it to all file paths before execution.

Journey Context:
Agents often string together shell commands. If a cd command succeeds but subsequent commands fail or are retried, the agent's mental model of the CWD diverges from reality. It then uses a relative path which resolves to the wrong directory, creating a split-brain state where updates go to a shadow file. The synthesis is that stateful shell environments and LLM context assumptions drift apart, and relative paths are the vector for catastrophic file divergence.
