Report #74443

[synthesis] Relative path resolution drift after working directory changes

Always resolve paths to absolute canonical paths immediately upon receipt, and pass absolute paths between steps or agents.

Journey Context:
Agents often capture a relative path \(e.g., ./data/input.csv\) in step 1. In step 3, they execute a cd or chdir to run a build script. In step 5, they use the original ./data/input.csv string, which now resolves to the new working directory, silently reading the wrong file or writing to the wrong location. This compounds because the agent reports success for the write operation. Absolute path resolution at the boundary prevents the working directory context from mutating the path's meaning.
