Generate a targeted overlay from the selected Go toolchain using the upstream fix for golang/go#81009. Remove the DCP-specific exec shim and add a Darwin child-process regression test that proves the overlay is active. Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com>
Build the signal regression launcher with the runtime overlay and have it start the observer through OSExecutor. This keeps the regression effective while allowing direct go test and IDE runs to use an unpatched test binary. Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com>
Document the generator transition checks and Darwin signal regression as temporary coverage to remove when DCP requires a Go release containing golang/go#81009. Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com>
The dcptun container client is built for Linux, so it does not need the Darwin runtime overlay or its generation prerequisite. Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com>

Make Git patch application independent of line-ending configuration, distinguish Git launch failures, remove overlay arguments from Linux-only helper builds, and improve the signal regression launcher's timeout and self-exec handling.
