8817d8f2f9 fix(grpc): enforce DNS message size limits (#7490) 
Add DNS wire size validation for requests/replies. Limit gRPC
recv/send via default call options, accounting necessary
framing/protobuf overhead. An error is returned for oversized
messages. Add test.

e1768a5d27 Merge commit from fork 
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.

2f981ff797 fix(forward): use netip package for parsing (#7472) 
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.

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.

60227bd8d2 perf(kubernetes): optimize AutoPath slice allocation (#7323) 
Pre-allocate slice capacity in AutoPath to eliminate unnecessary
memory reallocations. This avoids slice growth when appending
search domains and sentinel value.

Benchmark shows significant performance improvement:
- Before: 538.6 ns/op, 560 B/op, 13 allocs/op
- After:  436.8 ns/op, 336 B/op, 11 allocs/op
- Result: 19% faster, 40% less memory, 15% fewer allocations

The optimization benefits Kubernetes clusters using autopath for
server-side search path completion.

Adds benchmark test to measure AutoPath performance.
