lukaszraczylo 722e6f3d29 fix(retry): retries-after-first semantics, ctx-aware backoff, hardened classification ...

Critical: attempts now counts retries performed AFTER the first try
(default 1 -> two tries total), not the total try count. The prior
reading made retry:{enabled:true}'s own documented default perform zero
retries. (*retryPolicy).totalTries() is the single conversion point,
clamping any attempts<1 to 1 so do()'s loop bound can never compute <=0
and skip calling call() entirely (no (nil,nil) return path).

Backoff waits are now ctx-aware: sleepFn func(time.Duration) is replaced
by waitFn func(context.Context, time.Duration) bool, whose production
implementation (defaultWaitFn) selects between time.After(d) and
ctx.Done(). A context canceled mid-wait aborts the remaining retries
immediately instead of blocking out the full backoff.

Also: classify a request-build failure (invalid method/URL) as
non-transient via errRequestBuildFailed, since retrying an identically
malformed request only wastes attempts; drop the drain cap to a
dedicated 64KiB constant instead of the 32MiB response cap; fix a
t.Fatal call from a non-test goroutine in the mid-stream-death test;
drop the misleading omitempty on Config.Retry (a struct value is never
'empty' to encoding/json); document the Retry-After >2s-falls-back-to-
backoff behavior and cover it with a direct table test.

README: add the retry config table, a RetryConfig field reference, and
a Retry section documenting the semantics. examples/kubernetes.yaml
gains a retry block alongside its other optional sections.

Gate: go test -race, gofmt, vet, yaegi-check, golangci-lint (incl a
fieldalignment fix on two new test structs) all clean. 295 subtests
pass, 0 failed. integration/ untouched.
