Delete the SEA orchestrator (build.mjs), blob/inject steps, the build:native:sea/release scripts, and the blob/sea-config path helpers. Bun (build:native:bun) is now the only packaged engine.
- Remove the SEA build chain (build.mjs, 02-sea-blob, 03-inject, build:native:sea/release scripts, blob/sea-config path helpers) - Updater: drop the node:sea detection and the manifest platforms section — the bun section is the only source of update artifacts, and the stage default engine is bun - produce-manifest emits a bun-only manifest and fails on any missing target; native-manifest makes platforms optional and drops selectPlatformEntry - CI: the native bundle matrix now builds Bun binaries only; flake.nix compiles build:native:bun offline - Retire packages/kimi-build (its only consumer was the SEA injector) - Docs: Bun is the packaging engine everywhere (CONTRIBUTING en/zh, AGENTS.md); changeset for the engine switch
- release-artifacts tests now describe the bun-only manifest: full coverage required, missing targets listed in the error, platforms section gone - pin session_id in the builtin-tools projection test (sibling of the earlier isolation fix) - native-manifest test: bun section is the only lookup

执行 SEA 退役（runbook 阶段 2+3 合并执行）。用户群体极小（维护者 + 数人），保留期失去意义，直接一次切换。Follow-up to #5。
Problem
Bun 已是事实上的构建/发布引擎，但仓库里还并存着完整的 Node SEA 构建链、升级端的 SEA 检测分支和 manifest 的 platforms 段——双引擎并存的维护成本（两套构建、两套升级路径、CI 双 job）由所有人承担。
What changed
build.mjs、02-sea-blob.mjs、03-inject.mjs、build:native:sea/release脚本、blob/sea-config 路径助手；build:native:bun成为唯一打包引擎node:sea检测（source.ts、native-assets.ts）；manifest 的platforms段退场（schema optional、selectPlatformEntry删除），bun段是唯一更新产物来源；stage 默认引擎bunbun段，缺失任一目标即失败_native-build.yml只保留 Bun 六目标矩阵（SEA job 与build-sea/build-bun输入删除）build:native:bun验证
