ci(instrumentations): use supported Confluent Node versions

[BridgeAR]

What does this PR do?

Run Confluent instrumentation on Node 18, 20, and 22 for all supported package versions, and Node 24 for >=1.4.0.

Motivation

@confluentinc/kafka-javascript has no ABI 147 prebuild. Its source fallback fails under Node 26 because the librdkafka configuration header is not generated.

Additional Notes

Node 26 should be added after the Kafka-backed plugin suite can install, load, and connect there.

Benchmarks

Benchmark execution time: 2026-08-14 20:26:11

Comparing candidate commit 921cb06 in PR branch BridgeAR/2026-08-11-confluent-node-support with baseline commit 77cd463 in branch master.

📊 Benchmarking dashboard

Found 0 performance improvements and 0 performance regressions! Performance is the same for 2320 metrics, 38 unstable metrics.

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 ----------------------------------'

Unstable benchmarks

These benchmarks have a confidence interval too wide to call a change; treat them as noise rather than signal.

Shorten the matrix coverage flag

Because this job now has four matrix cells, All Green will see multiple coverage artifacts for the same integration and scripts/group-coverage.mjs keeps multi-cell integrations under their full stripped flag instead of bucketing them. This flag becomes instrumentations-instrumentation-confluentinc-kafka-javascript after the node version is stripped, which is 62 characters; the grouping script documents Codecov's 45-character flag limit and that overlong flags are silently dropped (scripts/group-coverage.mjs lines 42-44, 122-124), so the new Confluent instrumentation coverage will not be uploaded to Codecov. Use a shorter per-cell flag such as one based on confluentinc-kafka-javascript without the duplicated instrumentation prefix.
