fix(non-interactive-env): use export for env vars to apply to all chained commands

Previous `VAR=val cmd` format only applied to first command in chains.
New `export VAR=val; cmd` format ensures variables persist for all commands.

Also increased test timeouts for todo-continuation-enforcer stability.
