security: patch CVE-2026-111943

 ### Changed
 
+- Updated Go to 1.26.10 and the Alpine `ca-certificates-bundle` in Docker images to 20261020-r0 to stop trusting the compromised eMudhra CAs ([CVE-2026-111943](https://emudhra.we-have-a-problem.com/)).
 - HTTP requests now fail instead of hanging forever if the server does not start responding within 1 minute. Set the `SRC_RESPONSE_HEADER_TIMEOUT` environment variable to change this timeout, or to `0` to disable it. Responses that stream data for a long time (for example, large search job results) are not affected.
 - `src search-jobs logs` and `src search-jobs results` now use the standard API client, gaining proxy support, `-insecure-skip-verify`, and cross-host redirect protection, and now report an error on non-200 responses instead of writing the error page into the output.
 - The command list in `src help` is now generated from the registered commands instead of being maintained by hand. `src debug`, `src snapshot`, and `src lsp` now appear in it; aliases are shown after each description.
