Addresses issue #2016 where nodes behind unstable networks
(e.g. campus firewalls) cause excessive traffic that can freeze
the remote node.
Two changes in peer_ospf_route.rs:
- Make do_sync_route_info only trigger reverse sync_now when
incoming data actually changed the route table or foreign
network state. The previous unconditional sync_now created
an A->B->A->B ping-pong cycle on every RPC exchange.
- Add exponential backoff (50ms..5s) to session_task retry loop.
The previous fixed 50ms retry produced ~20 RPCs/s during
sustained network instability.
* machine-id should be scoped unbder same user-id
* feat: report device os metadata to console
* fix sync root key cause packet loss
* fix tun packet not invalid
* fix faketcp cause lat jitter
* fix some packet not decrypt
* fix peer info patch, improve performance of update self info
* fix foreign credential identity mismatch handling
- improve credential peer filtering and related route lookup behavior
- expose credential peer information through CLI and API definitions
- add and refine tests for credential routing and peer interactions
- add credential manager and RPC/CLI for generate/list/revoke
- support credential-based Noise authentication and revocation handling
- propagate trusted credential metadata through OSPF route sync
- classify direct peers by auth level in session maintenance
- normalize sender credential flag for legacy non-secure compatibility
- add unit/integration tests for credential join, relay and revocation
Enable encryption for non-direct nodes requiring relay forwarding.
When secure_mode is enabled, peers perform Noise IK handshake to
establish an encrypted PeerSession. Relay packets are encrypted at
the sender and decrypted at the receiver. Intermediate forwarding
nodes cannot read plaintext data.

This change introduces a major refactoring of the RPC service layer to improve modularity, unify the API, and simplify the overall architecture.
Key changes:
- Replaced per-network-instance RPC services with a single global RPC server, reducing resource usage and simplifying management.
- All clients (CLI, Web UI, etc.) now interact with EasyTier core through a unified RPC entrypoint, enabling consistent authentication and control.
- RPC implementation logic has been moved to `easytier/src/rpc_service/` and organized by functionality (e.g., `instance_manage.rs`, `peer_manage.rs`, `config.rs`) for better maintainability.
- Standardized Protobuf API definitions under `easytier/src/proto/` with an `api_` prefix (e.g., `cli.proto` → `api_instance.proto`) to provide a consistent interface.
- CLI commands now require explicit `--instance-id` or `--instance-name` when multiple network instances are running; the parameter is optional when only one instance exists.
BREAKING CHANGE:
RPC portal configuration (`rpc_portal` and `rpc_portal_whitelist`) has been removed from per-instance configs and the Web UI. The RPC listen address must now be specified globally via the `--rpc-portal` command-line flag or the `ET_RPC_PORTAL` environment variable, as there is only one RPC service for the entire application.

QUIC proxy works like kcp proxy, it can proxy TCP streams and transfer data with QUIC.
QUIC has better congestion algorithm (BBR) for network with both high loss rate and high bandwidth.
QUIC proxy can be enabled by passing `--enable-quic-proxy` to easytier in the client side. The proxy status can be viewed by `easytier-cli proxy`.
- **fix deadlock in ospf route introducd by #958 **
- **use random peer id for foreign network entry, because ospf route algo need peer id change after peer info version reset. this may interfere route propagation and cause node residual**
- **allow multiple nodes broadcast same network ranges for subnet proxy**
- **bump version to v2.3.2**
sometimes route table may not be updated in time, so some dead nodes are still showing in the peer list.
when generating ipv4-peer table, we should avoid these dead devices overrides the entry of healthy nodes.
this may fix following problem:
1. cpu 100% when large number of nodes in network.
2. high cpu usage when large number of foreign networks.
3. packet loss when new node enters/exits.
4. old routes not cleand and show as an obloleted entry.
This patch implements:
1. A dns server that handles .et.net. zone in local and forward all other queries to system dns server.
2. A dns server instance which is a singleton in one machine, using one specific tcp port to be exclusive with each other. this instance is responsible for config system dns and run the dns server to handle dns queries.
3. A dns client instance that all easytier instance will run one, this instance will try to connect to dns server instance, and update the dns record in the dns server instance.
this pr only implements the system config for windows. linux & mac will do later.
