Bumps github.com/quic-go/quic-go from 0.55.0 to 0.56.0.

Release notes

Sourced from github.com/quic-go/quic-go's releases.

v0.56.0

This release introduces qlog support for HTTP/3 (#5367, #5372, #5374, #5375, #5376, #5381, #5383).

For this, we completely changed how connection tracing works. Instead of a general-purpose logging.ConnectionTracer (which we removed entirely), we now have a qlog-specific tracer (#5356, #5417). quic-go users can now implement their own qlog events.

It also removes the Prometheus-based metrics collection. Please comment on the tracking issue (#5294) if you rely on metrics and are interested in seeing metrics brought back in a future release.

Notable Changes

  • replaced the unmaintained gojay with a custom, performance-optimized JSON encoder (#5353, #5371)
  • quicvarint: improved panic message for numbers larger than 2^62 (#5410)

Behind the Scenes

Go 1.25 introduced support for testing concurrent code using testing/synctest. We've been working on transitioning tests to use synctest (#5357, #5391, #5393, #5397, #5398, #5403, #5414, #5415), using @​MarcoPolo's simnet package to simulate a network in memory.

Using synctest makes test execution more reliable (reducing flakiness). The use of a synthetic clock leads to a massive speedup; the execution time of some integration tests was reduced from 20s to less than 1ms. The work will continue for the next release (see tracking issue: #5386).
