feat(runtime-host): discover coordination relays automatically

[M4n5ter]

English

Summary

• Discover public Circuit Relay v2 candidates through a bounded, client-only IPFS Amino DHT swarm
• Keep reservation authority in the main peer endpoint, prefer manually configured relays, and publish only accepted reservations
• Enable best-effort discovery by default for managed peer Hosts, with explicit Desktop and CLI opt-out

Refs #3842

Verification

• Rust formatting, Clippy, 9 native tests, cargo-deny, dependency and notice gates
• Build, typecheck, lint, format, Knip, ASF source/header, release, Astryx, and Storybook gates
• Full Runtime Host suite (1,347 passed) and Desktop suite (1,672 passed)
• Focused management, framing, native-peer, and SSH suites (60 passed)
• A real public-network run accepted reservations from two distinct Relay v2 peers
• Desktop Settings flow inspected in the development build

摘要

• 通过有界且仅作客户端使用的 IPFS Amino DHT swarm 发现公共 Circuit Relay v2 候选节点
• reservation authority 仍只属于主 peer endpoint；手动配置的 Relay 优先，且只发布已接受 reservation 的节点
• managed peer Host 默认启用尽力而为的自动发现，并在 Desktop 与 CLI 提供明确的关闭方式

Approved at exact head 61c56bd4a52b2c29c74e0347d3bfd368b99c2a86; I found no P0–P2 issues.

I traced the discovery path from the bounded, client-only DHT swarm through relay probing, reservation acceptance, and signed Peer Mesh route publication. The main peer endpoint remains the reservation authority, manually configured relays count first toward the target, and only validated addresses from accepted reservations enter the published route set. The implementation also provides Desktop and CLI opt-out controls while keeping the legacy peer-management frame compatible through an optional field and capability-gated status request.

Verification passed on the exact head: the root build and 60 focused Runtime Host, CLI, and Desktop tests completed successfully, and Rust formatting is clean. Local Rust tests could not run because this machine has Rust 1.95 while the crate requires 1.98; the exact-head hosted native-addon builds, test, quality, package, windows_recovery, and installed-CLI validations all completed successfully (the Eval validation job was skipped by its workflow). A synthetic merge with current main at c314e9eb0b96e10abfa35f10965e8cc9d2fc7b9e is clean and its full root build passes.
