[synthesis] Relative file paths resolve to wrong locations because agent assumed working directory persisted across tool calls

Always resolve and use absolute paths for every file operation. Never assume the working directory is stable across tool calls—explicitly verify cwd before each operation or avoid relative paths entirely.

Journey Context:
An agent runs \`cd /project/src\` in one tool call, then uses \`cat utils/helpers.py\` in the next, expecting to read \`/project/src/utils/helpers.py\`. But many agent frameworks execute each tool call in a fresh shell or reset the working directory, so the second call resolves to \`/project/utils/helpers.py\`—a different file that may not even exist, or worse, a file that does exist but has different contents. The agent reads the wrong file, makes edits based on wrong context, and by step 7 has created a parallel incorrect directory structure. The compounding is insidious because each step reports 'success'—the agent is just operating on the wrong files. The alternative of tracking cwd in agent state is fragile; absolute paths are the only invariant that survives framework resets, subprocess boundaries, and multi-agent handoffs.
