refactor(notify): extract handler, rule, util

Split the monolithic notify module into three submodules:
- `handler`: async bucket dispatch with cooldown, retry, escalation
- `rule`: rule parsing from YAML config, template merging, overrides
- `util`: validation, event timing, helper functions
  `NotificationTemplateDef` replaces `AddAssign` with `apply()` for
  non-destructive merging (self wins, other fills gaps).
  `insitenotify` logs instead of panicking.

 ## ANTI-PATTERNS (THIS PROJECT)
-
+1. **Hardcoded user** — "vulcan" username hardcoded throughout prebake
-1. **Python in Rust project** — workshop-baker has Python tests (pytest.ini, test_prebake.py)
+2. **Unsafe libc** — workshop-baker/src/prebake/security.rs has 5+ unsafe blocks
-2. **temp/ directory** — Non-standard in Rust projects
+3. **Rust 2024 edition** — May not work with stable toolchains
-3. **Certificates in source** — artifact workshop-cert/certs/ not excluded 
+4. **Empty daemon** — `daemon/` dir is empty, Daemon command is `unimplemented!()`
-4. **Deprecated projects** — workshop-executor.old, workshop-monitor.old still present
-5. **Hardcoded mirrors** — Tsinghua University mirrors in configs
-6. **Rust 2024 edition** — May not work with stable toolchains
 
 ## UNIQUE STYLES
-
 - **Pipeline DSL**: Shell scripts with `# @decorator` annotations
-- **Dual-mode baker**: CLI commands + daemon mode
+- **Notification system**: Plugin-based with batching, retry, priority groups
-- **LLM cookbook system**: YAML cookbooks for language-specific builds
+- **LLM cookbook system**: YAML cookbooks for language-specific builds (archived)
 - **Chinese docs** — Documentation primarily in zh-CN
-- **User "vulcan"** — Custom build user (not root/runner)

 ## NOTES
-
 - **Docker required** for integration tests
-- **workshop-builder-native** is a stub (3-line Hello World)
+- **No root workspace** — each crate independent, build separately
-- No root workspace Cargo.toml — each crate is independent
+- **7 archived crates** — workshop-agent, workshop-cert, workshop-deviceid, workshop-helper-mac, workshop-llm-detector, workshop-pipeline, workshop-vault
-- `AGENTS.md.old` at root — legacy documentation
+- **Python tests removed** — pytest.ini exists but test files no longer in workspace

+# Resource 模型
+
+## 核心思想
+
+整个系统只关心两件事：东西从哪来（fetch），东西到哪去（publish）。
+
+fetch 方向：URL → 本地路径 → 使用。
+publish 方向：本地路径 → 变换（插件）→ URL。
+
+两个方向共用同一套寻址方式，但 Resource 中间态只存在于 fetch 方向。
+
+## URL 格式
+
+```
+getter::url?param1=value1&param2=value2
+```
+
+getter 显式声明意图。不是"我猜这是个 git 仓库"，而是"使用者告诉我这是什么"。
+
+只有三个 getter：
+
+- `git` — 克隆仓库，必要时 checkout 指定版本
+- `http` / `https` — 下载文件，必要时校验 checksum
+- `file` — 复制本地文件或目录
+
+版本锁定不用 `@v1.0`（`@` 在 URL 里是认证分隔符），用 `?ref=v1.0`。
+
+没有 `github.com/user/repo` 看起来应该 clone 它这种黑魔法。
+没有 `.tar.gz` 看起来应该解压它的惊喜。
+URL 是 URL，行为是行为，两者用 getter:: 显式绑定。
+
+## Resource 不是网络地址
+
+流水线阶段（prebake / finalize / notify）只接触 Resource：一个名字 + 一个本地路径，已就绪。它们不经由网络、不解析 URL、不碰 getter。
+
+所有 fetch 行为在阶段启动前完成：
+
+- worker 模式：bakerd fetch → 填入 ResourceRegistry → 启动 baker
+- standalone 模式：baker 自己 fetch → 填入 ResourceRegistry → 执行阶段
+- bare 模式：不 fetch，传入的必须是 Resource
+
+ResourceRegistry 是名字到路径的映射。填进去就只读了。
+
+## getterurl 是独立的 crate
+
+URL 格式解析 + 基本 fetch 放在 workshop-getterurl，和 baker 本身没有耦合。任何人都可以用。
+
+crate 分两层：
+
+```
+结构层（parser）：
+  "git::https://host/repo.git?ref=v1.0" → { getter: "git", url: Url, params: Params }
+
+获取层（builtin getters）：
+  getter.fetch(url, params, dst) → local_path
+  git:   git clone + optional checkout
+  http:  HTTP GET + optional checksum
+  file:  std::fs::copy
+```
+
+获取层是字面意义的——不解压、不推断、不猜意图。
+
+## Checksum
+
+checksum 作为 URL query 参数传递。三态语义：
+
+- `?checksum=sha256:abc` — 必须匹配
+- `?checksum=` — 显式禁用校验
+- 无 checksum — 如果服务端返回 Content-Digest 头，校验它
+
+getter 不主动校验，它只执行 URL 里指定的操作。
+
+## Artifact 不经过 Resource
+
+artifact 是 bake 的产物，自产生就开始被使用，不存在中间态。它的路径就是 bake 产出的本地路径，不走 ResourceRegistry。
+
+artifact 的 publish 方向由插件定义行为——可能上传、可能扫描、可能只记录。插件定义最终的行为，只要是自洽的。
+
+## 三种运行模式
+
+```
+               fetch 执行者      fetch 在阶段内
+daemon 模式    bakerd            否
+standalone     baker 自身        否（阶段启动前已完成）
+bare 模式      无                否（必须传入 Resource）
+```
+
+bare 模式下传入的必须是已经就绪的 Resource。外部 URL 是 daemon 或 standalone 的事，bare 不负责。

 ## CONVENTIONS
-
 - **ExecutionContext**: Passed through all stages, carries task_id, username, env_vars, timeout
-- **PrebakeStage**: Ordered enum controlling stage execution sequence (Bootstrap -> Ready)
+- **PrebakeStage**: Ordered enum Bootstrap→EarlyHook→DepsSystem→DepsUser→LateHook→Ready
-- **Decorator**: Attached to shell functions via `# @name(args)` comments above function declarations
+- **Decorator**: `# @name(args)` comments above shell function declarations
-- **Engine**: Lightweight wrapper around cgroup manager for resource isolation
+- **Notification**: Plugin-based dispatch with batching, exponential backoff, priority groups
-- **Dual-mode**: CLI commands (prebake, bake, finalize) vs daemon mode via Unix socket
+- **Engine**: Delegated to `workshop-engine` crate (formerly in-tree)
+- **Dual-mode**: CLI commands (standalone) vs Daemon mode (unimplemented)
+
+## ANTI-PATTERNS
+1. **Empty daemon/** directory — Daemon command is `unimplemented!()`
+2. **Dead code allowed** — `lints.rust.dead_code = "allow"` in Cargo.toml
+3. **Engine was extracted** — workshop-engine is its own crate now, src/engine/ removed
+4. **Python test infra exists but files removed** — pytest.ini remains, test dir is empty

 ## WHERE TO LOOK
-
 | Task | Location |
 |------|----------|
-| Config loading | `config.rs` - FinalizeConfig |
+| Config loading | `config.rs:17` - `FinalizeConfig` + `parse()` |
-| Email notify | `plugin/internal/mail/` - SMTP templates |
+| Plugin registration | `plugin.rs` - `register()` |
+| Email notifications | `plugin/internal/mail.rs` - SMTP |
 | Webhooks | `plugin/internal/webhook.rs` |
-| Artifact fetch | `plugin/fetch/` - git/http/extract |
+| Satori integration | `plugin/internal/satori.rs` |
-| Checksums | `plugin/fetch/checksum.rs:13` - SHA1 deprecated |
+| Shell plugins | `plugin/shell.rs` |
+| Template rendering | `template.rs` - `{{VARIABLE}}` handlebars-style |
 
 ## CONVENTIONS
-
+- **Plugin System**: `FinalizePlugin` trait + registry with both internal and dynamic plugins
-- **Plugin System**: Dynamic + internal plugins via Plugin trait
+- **Template Syntax**: `{{VARIABLE}}` handlebars-style substitution via `template.rs`
-- **Template Syntax**: `{{VARIABLE}}` handlebars-style
+- **Stages**: EarlyHook → (Artifacts) → LateHook → Notifications
-- **Stages**: Hook → Fetch → Build → Publish → Notify → Cleanup
+- **Notification**: `notify.rs` in parent module drives plugin-based notification dispatch
-- **Fetch**: Supports git, http, with extraction and checksum verify
+- **ResourceRegistry**: Shared resource cache passed through to plugins
 
 ## ANTI-PATTERNS
-
+1. **fetch/ subdirectory removed** — was `plugin/fetch/{git,http,extract,checksum}`, no longer exists
-1. **SHA1 deprecated** — `checksum.rs:13` warns SHA1 is deprecated
+2. **SHA1 deprecated** — workshop-getterurl handles checksums now
-2. **Unimplemented** — `rhai.rs:17` - "todo!()" for Rhai scripting
+3. **Unimplemented** — `rhai.rs:17` - "todo!()" for Rhai scripting
-3. **TODO markers** — Multiple TODOs in config.rs (lines 305-306)
+4. **TODO markers** — Multiple TODOs in config.rs (lines 305-306)
+5. **Artifact stage not implemented** — `finalize.rs:57` — "TODO: artifact stage implementation"
