fix(m190): r1 复审——0x01 修成 \1 + YAML 门禁、被调方声明 secret、拆两个超限测试文件、验签换 ed25519-dalek

四条 P1 + 四条 P2 一并处置(不变的是判据,变的是「谁在承重」)。

P1-1 `.github/workflows/release-build.yml` 的 sed 替换串是裸 0x01(本意 `\1`):GitHub 解析该文件会
失败 ⇒ 整个 run 起不来;即便容忍,版本号也会被求值成单字节,PE 判据报「与 Cargo.toml 不同源?」把
排障引向错方向。修成字面 `\1`,并新增 `packaging/check_workflows_yaml.py`(真 YAML 解析器 parse
全部 workflow + 裸 C0 控制字符字节判据;带 --self-test 注入 0x01/坏结构断言必红),接进
`release-guard.yml` 两步。文本扫描型守卫看不见这类字节,这道门禁专门挡它。

P1-2 `release-publish.yml` 没在 `on.workflow_call.secrets` 里声明 `ULL_MANIFEST_SIGNING_KEY`,调用方
却传了:可复用工作流只拿得到自己声明过的 secret ⇒ 用户配好钥也会在签名步红,而错误文案反过来指控
Secret 没配。补声明(required: false,fail-closed 由步内 ::error:: + exit 1 承担,同
ULL_MSA_CLIENT_ID 的模式)。

P1-3 两个测试支撑文件越过 400 行守卫:签名夹具拆到 `tests/support_sign.rs`(support.rs 458→392),
CLI e2e 的签名部分拆到 `support/update_e2e_sign.rs`(update_e2e.rs 406→348)。纯搬家。

P2-2 「唯一收口点」改成结构事实:从 `UpdateSource` 删掉 `fetch_manifest` 默认实现,调用方只能拿
`verified_manifest(&source, channel)`(源只交原文,想绕过验签就得自己重写解析与渠道判据)。
P2-3 文档写的第 ④ 条命令补进流水线:`sign_manifest.py --verify-pinned` 用 trust.rs 里钉住的公钥
回验刚落盘的 .sig(不碰私钥),发布侧因此验证的是「客户端的判据」而不是「签名脚本的自我声明」。
P2-4 随自写实现一起删除(`Fe` 的错误 PartialEq 不再存在)。
P2-5 app-iced/build.rs 注释里那个 windows_subsystem 属性本分支不存在(M196 才有),改为说明
「本文件只写版本资源,子系统由 rustc 属性决定,check_pe_version.py 会把 subsystem 打出来」。
P2-6 坏清单不再带 error.path 是有意降级(来源 id 在 message 里),保持。

裁定项:自写 Ed25519 换成 `ed25519-dalek::verify_strict`(信任锚不许自写密码学;此刻信任表还是空表,
零兼容负担)。删除 `update/ed25519/{field,group,mod}.rs`(含只服务它们的单测),新 `update/ed25519.rs`
只剩一个薄封装;拒绝类用例(可锻 S+L / 小阶公钥 / 非规范 R / 空签名 / 未知 key)**一条没删**,
改成钉 dalek 的 strict 语义——实测 dalek 对全部五类的结论与旧实现一致(非规范 R 的拒绝理由不同:
dalek 走「小阶点」而非「编码非规范」,用例注释里写明)。签名侧留在 `packaging/ed25519_ref.py`
(纯 Python、零 pip 依赖),`--self-test` 用 RFC 8032 同一组向量钉两边。

//!
//! 这一组用例是自写密码学的**唯一**公信力来源:向量来自 RFC 附录(不是自己签自己验),

//! 非规范 R 编码 / 空签名)。
//! M190 r1 复审把自写曲线算术整体换成了官方实现(理由见 `crate::update::ed25519` 的模块文档)。

//!
//! | 用例 | 它挡住什么 |
//! |---|---|
//! | `rfc8032_vectors_verify` | 实现换成任何一个错的版本(向量是 RFC 附录的,不是自签自验) |
//! | `malleable_s_plus_l_is_rejected` | 把 `verify_strict` 换成 `verify`(后者不检查 `S` 规范性) |
//! | `small_order_public_key_is_rejected` | 同上:小阶公钥/小阶 `R` 在 `verify` 下能「自洽通过」 |
//! | `non_canonical_r_encoding_is_rejected` | 非规范编码的点(`y >= p` 的第二种写法) |

//! | `signing_key_round_trips` | 测试夹具(dalek `SigningKey`)与验签侧是同一套语义 |
//!
//! 每条都实测过 dalek 2.2 的**实际**行为;与「RFC 最低要求」不同之处在用例注释里写明(见

"""Parse every workflow file with a **real YAML parser** (M190 r1 复审 P1-1).
Why this exists: a raw 0x01 byte slipped into `.github/workflows/release-build.yml` (a `sed` replacement
string that should have been `\\1`). GitHub refuses to parse such a file, so the whole run would not even
start — and no other guard noticed, because they all read workflow files as *text* (`check_release_semantics.py`
does `yaml_scalars()`, the file-size job only counts lines). A text scanner cannot see a control byte that
a YAML 1.2 reader rejects outright.
So: hand every `.github/workflows/*.yml` to PyYAML. Two checks, both cheap:
① it parses (real error message with position, not a mystery red);
② no C0 control character other than TAB/LF/CR is present (YAML 1.2 forbids them; parsers differ in
whether they reject, so this is the belt-and-braces half).
PyYAML is preinstalled on GitHub-hosted runners; if it is not, this script installs it. If that fails too
the gate **fails** rather than degrading to a text scan ("工具缺失也 fail" — same rule as the other guards).
