Merge branch 'main' into policy/scope-golangci-rule-to-vendored-copies

Stated unqualified, the rule forbade an agent from modifying
.golangci.yml anywhere, including the canonical copy in this repo --
the only place it can be fixed. Compliance and remediation were
mutually exclusive.

Scope the prohibition to the vendored copy in a consuming repo, which
is the property the rule exists to protect, and name the one legitimate
path for change: a PR against canonical here, merged only by the user.

 # Completed Steps
 
-- 2026-09-03: Added `-count=1` to both `go test` invocations in the canonical Go
-  `make test` example in `REPO_POLICIES.md`, so the target cannot report a
-  cached pass it did not earn, and documented that Go's test-result cache is a
-  second, independent cache stacked below the Docker layer cache.
 - 2026-08-07: Set the canonical `.golangci.yml` to the org-standard v2-schema
   config already deployed byte-identical across the org's Go repos (settings
   under `linters.settings` so thresholds like lll/funlen/cyclop/dupl actually

-    `-count=1` is required on both invocations: it defeats Go's test _result_
-    cache, so the target cannot report a pass it did not earn, and the rerun
-    reproduces a failure instead of replaying it. It leaves the build cache
-    alone, so it costs the runtime of the suite and no recompilation.

-    Note that this is a second, independent cache, stacked below the Docker
-    layer cache that [issue #26](https://git.eeqj.de/sneak/prompts/issues/26)

-    it does not guarantee `go test` inside that step does any work, because the
-    `GOCACHE` baked into earlier image layers survives into the re-executed
-    step. They are two separate defects requiring two separate fixes, and a fix
-    for one must not be recorded as covering the other.
