Regenerates lib/include/public/Version.hpp to the next date-derived release version **3.10.267.1** (3.<(year-2020)+4>.<dayOfYear>.1), produced by tools/gen-version.cmd.

Only the generated version header changes:

```diff
-#define BUILD_VERSION_STR "3.10.240.1"
+#define BUILD_VERSION_STR "3.10.267.1"
```

Standard release-prep PR (same shape as #1527). After this merges to `main`, publish the `v3.10.267.1` tag as a non-draft, non-prerelease GitHub Release. That release event triggers the automated `cpp-client-telemetry` vcpkg port bump workflow.
