ci: install ddtest 1.7.0 and riot 0.23.0 in testrunner image

[gnufede]

Update the testrunner Dockerfile to:

• Bump riot from 0.22.0 to 0.23.0
• Install ddtest 1.7.0 (pre-built binary from GitHub releases)

Update ci/requirements/ci.txt to pin riot==0.23.0 (with correct hash).

This is a prerequisite for the ddtest dogfooding PR (#19870): once the testrunner image is rebuilt with these changes, ddtest is available in PATH and the .ddtest_build CI job can be removed.

NOTE: the testrunner image hash in .gitlab/testrunner.yml must be updated after the image is rebuilt.

Benchmarks

Benchmark execution time: 2026-08-31 12:15:26

Comparing candidate commit 0f12a37 in PR branch gnufede/testrunner-ddtest-riot with baseline commit 88029de in branch main.

📊 Benchmarking dashboard

Found 0 performance improvements and 6 performance regressions! Performance is the same for 574 metrics, 10 unstable metrics, 2 known flaky benchmarks, 16 flaky benchmarks without significant changes.

Explanation

This is an A/B test comparing a candidate commit's performance against that of a baseline commit. Performance changes are noted in the tables below as:

• 🟩 = significantly better candidate vs. baseline
• 🟥 = significantly worse candidate vs. baseline

We compute a confidence interval (CI) over the relative difference of means between metrics from the candidate and baseline commits, considering the baseline as the reference.

If the CI is entirely outside the configured SIGNIFICANT_IMPACT_THRESHOLD (or the deprecated UNCONFIDENCE_THRESHOLD), the change is considered significant.

Feel free to reach out to #apm-benchmarking-platform on Slack if you have any questions.

More details about the CI and significant changes

You can imagine this CI as a range of values that is likely to contain the true difference of means between the candidate and baseline commits.

CIs of the difference of means are often centered around 0%, because often changes are not that big:

---------------------------------(------|---^--------)-------------------------------->
                              -0.6%    0%  0.3%     +1.2%
                                 |          |        |
         lower bound of the CI --'          |        |
sample mean (center of the CI) -------------'        |
         upper bound of the CI ----------------------'

As described above, a change is considered significant if the CI is entirely outside the configured SIGNIFICANT_IMPACT_THRESHOLD (or the deprecated UNCONFIDENCE_THRESHOLD).

For instance, for an execution time metric, this confidence interval indicates a significantly worse performance:

----------------------------------------|---------|---(---------^---------)---------->
                                       0%        1%  1.3%      2.2%      3.1%
                                                  |   |         |         |
       significant impact threshold --------------'   |         |         |
                      lower bound of CI --------------'         |         |
       sample mean (center of the CI) --------------------------'         |
                      upper bound of CI ----------------------------------'
