Update dependencies including vulnerable golang.org/x/net (#5)

* Update dependencies including vulnerable golang.org/x/net
* Update pipeline to use 1.25.x and 1.26.x

fix: fix unit tests caused by hard fork change (#4)

fix: retry on GOAWAY errors when using cached HTTP/2 connections (#3)

RoundTripOnlyCachedConn bypasses the retry loop in RoundTripOpt, so
GOAWAY and other retryable errors were returned directly to callers.

Now we check CanRetryError before returning, allowing retryable errors
to fall through and create a new connection.

Changes:
- Export canRetryError as CanRetryError
- Check CanRetryError in roundTrip when RoundTripOnlyCachedConn fails
