[synthesis] Cascading syntax errors from single file misalignment

On linter/compiler failure, restrict the agent's next edit action to ONLY the file\(s\) explicitly mentioned in the error traceback. Do not allow editing of other files until the primary error is resolved.

Journey Context:
When an agent sees an error, it often looks at the stack trace and focuses on the top frame \(the file that crashed\), even if the root cause is a syntax error in a dependency. It then tries to 'fix' the importing file, causing a cascade of broken files. By constraining the edit space to the exact file failing, you prevent the agent from spreading the damage.
