Skip the verbose test rerun after a timeout (closes #61)

A hung test used the 90-second backstop twice, because the verbose
rerun waited for the same hang. The Go recipe now looks in the first
run's output for the lines Go prints for a hang, and exits 1 with no
rerun. A failure with neither line in its output still reruns with -v.

The Python make test example takes the same timeout wrapper as its
Dockerfile example. The 60 and 90 second rule and the 5-minute rule say
a hung package uses the backstop once. The Go item in both repo
checklists now asks for this.

 # Completed Steps
 
+- 2026-11-03: A first test run that timed out now gets no verbose rerun
+  (https://git.eeqj.de/sneak/prompts/issues/61), on sneak's approval at
+  https://git.eeqj.de/sneak/prompts/issues/61#issuecomment-165195. The Go recipe
+  in `REPO_POLICIES.md` looks in the first run's output for
+  `panic: test timed out` or `*** Test killed`, and exits 1 when either is
+  there. The Python `make test` example takes the same `timeout 90 sh -c`
+  wrapper as its `Dockerfile` example. The 60 and 90 second rule and the
+  5-minute rule now say a hung package uses the backstop once. The Go item in
+  both repo checklists now asks for this, so a repository with the old recipe
+  fails it.
