Problem: skip-subnets only excludes inbound traffic, so outbound packets destined for those subnets are still redirected through the proxy. Solution: add explicit inbound and outbound subnet options while preserving skip-subnets as the backwards-compatible inbound setting. Validation: go test ./pkg/iptables ./proxy-init/cmd Signed-off-by: hooiv <125276621+hooiv@users.noreply.github>

Problem
The existing
--subnets-to-ignoreoption only adds source-subnet RETURN rules to the inbound chain. Outbound traffic to the same subnets is still redirected through the proxy.Solution
Add
--inbound-subnets-to-ignoreand--outbound-subnets-to-ignore. The legacy option remains supported as an inbound-only setting. Outbound exclusions match destination addresses.This is the proxy-init implementation for linkerd/linkerd2#10726; the injector and chart wiring are submitted separately.
