Instead of casting lease ID to uint32, fix the TTL() function
to use etcd time-to-live API for determining TTL. Add configurable
min-lease-ttl and max-lease-ttl options to prevent extreme TTL
values. By default, lease records now go through bounds checking
with 30s to 1d as the min/max.
Added unit tests for validation and docs.

Add ReadTimeout, WriteTimeout, and IdleTimeout (5s each) to metrics HTTP
server and test to verify timeout behavior prevents hanging connections.

Replace manual host:port parsing using net.SplitHostPort +
strconv.ParseUint with the standard library net/netip function
ParseAddrPort. This eliminates integer conversion warnings and
improves type safety.

- Upgrade dd-trace-go dependency to v2.2.2
- Separate Zipkin and DataDog code paths for better maintainability
- Add proper tracer shutdown through OnShutdown()
- Replace deprecated opentracer.New() with direct tracer.Start()
- Added tests

Enable protogetter in golangci config and update all protobuf field
access to use getter methods instead of direct field access.
Getter methods provide safer nil pointer handling and return
appropriate default values, following protobuf best practices.

Enable intrange linter to enforce modern Go range syntax over
traditional for loops, by converting:
for i := 0; i < n; i++
to:
for i := range n
Adding type conversions where needed for compatibility
with existing uint64 parameters.

Enable canonicalheader linter to enforce proper HTTP header casing.
This ensures headers use Go's canonical format (e.g., "Content-Type"
instead of "content-type") for consistency.
Fixes header casing in DoH implementation.

Ensure Dial exits early or returns error when Transport has been
stopped, instead of blocking on the dial or ret channels. This removes
a potential goroutine leak where callers could pile up waiting
forever under heavy load.
Add select guards before send and receive, and propagate clear error
values so callers can handle shutdown gracefully.

Add test suite covering thread-safe random number generator with
tests for:
- Constructor with various seed values (positive, zero, negative)
- Deterministic behavior verification with same seeds
- Permutation generation and validation
- Concurrent access safety with multiple goroutines
- Mixed operations under concurrent load
Also clarify package documentation to explicitly state this is
for load balancing and server selection, not cryptographic use.
The math/rand usage is intentional for performance in non-security
contexts like upstream server selection and DNS record shuffling.

Enable copyloopvar linter and remove redundant variable
shadowing in Kubernetes plugin metadata handling. This pattern is
no longer needed in Go 1.22+ where loop variables are automatically
captured correctly in closures.

Enable the usetesting linter in golangci.yml configuration to
enforce proper testing practices. Replace manual temporary
directory and file creation with t.TempDir() in test files.
This improves test reliability by ensuring proper cleanup and
follows Go testing best practices.

Add conditional test skipping for bind and readme tests that rely on
Linux-specific loopback interface behavior. These tests reference
network configurations that may not exist on for e.g. macOS or other
platforms, causing spurious test failures.
