Report #98099

[synthesis] Agent writes to a path one directory off because a prior \`cd\` failed silently, corrupting or shadowing the wrong files

Use absolute paths derived from a single canonical base variable, and make \`cd\` failures fatal with \`cd /path \|\| exit 1\`; never chain relative-path operations across multiple shell calls without re-anchoring.

Journey Context:
A relative path in step 1 is correct only if the working directory is exactly what step 0 left. When \`cd\` fails silently \(e.g., directory was deleted\), the agent keeps writing to the parent or sibling directory. The wrong fix is to add more \`cd\` calls; the right fix is to eliminate dependency on the process cwd by resolving absolute paths once and passing them explicitly.
