docs: give subsystems/ its own README index; retire the data-structures-catalog framing

Browse Source 
core.md doubled as the folder index: its intro claimed "this folder catalogs the data structures" and carried the 38-row page table, wording that predates the one-page-per-subsystem shape where every page also carries its generated Cordis surface. The folder index now lives in docs/subsystems/README.md (page table plus the type-equiv note), and core.md is one subsystem page among siblings: the spine vocabulary. Structural referents move with it: the docs/AGENTS.md tier table and update rule, development.md's type-equiv pointer, the dsh-code-review skill, the two owning catalog Agent Notes, and website/docs.ts (README projects as reference/subsystems/index.md and takes the docs/subsystems folder alias; sidebar orders shift by one). Remaining "data-structure catalog" / "sub-page" phrasing in active notes and READMEs is reworded to subsystem-page terms in both languages; touched pairs re-recorded; translation-prompt snapshot re-recorded (its example embeds development.md).

# Subsystems
English | [中文](README.zh.md)
One page per subsystem of the DeepSeek Harness: what it is, the data structures it moves, and — where a `ctx` service or event scope backs it — a generated **Cordis surface** section carrying its service and event reference. The folder complements [architecture.md](../architecture.md), which describes *behavior* across subsystems (the service map, the session/turn/step lifecycle, the event taxonomy); each page here is the reference for one subsystem's vocabulary and wiring.
| Page | Owns |
|---|---|
| [core.md](core.md) | the spine vocabulary every turn traffics in — `Message`/`ContentBlock`, `StreamChunk`, `SessionEvent`, the `Agent` handle, `ToolDefinition`, branded ids, the `…Map → derived-union` pattern |
| [llm-streaming.md](llm-streaming.md) | the `StreamChunk` wire protocol + adapter contract, `BlockAssembler`, the `LlmAdapter` seam |
| [token-meter.md](token-meter.md) | immutable scalar and positional replay measurements with consumed-log revisions |
| [scope.md](scope.md) | scoped registration identity, dispatch carriers, and the owned `Scope` context |

| [persistence.md](persistence.md) | the durability seam: `SessionPersistence`, JSONL + SQLite backends, `session/flush`, crash recovery, `SessionHeader` |
| [settings.md](settings.md) | the user-settings seam: `SettingsNamespace` registration, layered resolution (defaults → composition `base` → user document), owner scopes, hot commits |
| [credentials.md](credentials.md) | the credential seam: `CredentialRef` references (never values) in configuration, per-operation resolution, UI-safe `CredentialInfo`, provider source layers |
| [session-query.md](session-query.md) | logical records, bounded exact-event reads, relationship traces, semantic filters/documents, and full-text result pages |
| [session-title.md](session-title.md) | durable title snapshots, source provenance, and the asynchronous provider contract |
| [system-prompt.md](system-prompt.md) | per-assembly context, tool-provider results, prompt sections, and cooperative assembly |
| [tools.md](tools.md) | `ToolDefinition` full fields, the schema DSL, `ToolExecution`/`ToolResult`, tool-presentation UI types, and the guarded execution pipeline |
| [user-interaction.md](user-interaction.md) | the UI-backed human question/answer seam: `AskUserQuestionRequest`, answer/options vocabulary, provider API, error taxonomy |
| [approval.md](approval.md) | the one-shot user-approval seam: `ApprovalRequest`, `ApprovalOutcome`, per-session policy, audit and answerer contracts |

| [code-runtime.md](code-runtime.md) | the code-execution seam: `CodeRunRequest`/`Result`, binding namespaces, captured logs, the `CodeRunFailure` taxonomy |
| [filesystem.md](filesystem.md) | the filesystem seam: `FsTarget`, read/write/edit outcomes, observed-file state, `FsErrorCode` |
| [lsp.md](lsp.md) | the LSP navigation seam: `LspQueryRequest`/`Result`, `LspProvider`/`Service`, four operations, `LspError` |

1. 它流经 agent loop 主干——循环在每个轮次中持有、派生、流式输出或记录它（`Message`、`StreamChunk`、`SessionEvent`、`Agent` 句柄本身），与当前加载了哪些插件无关；**或者**
2. 它是插件作者面向某条流水线编写的代表性类型——`ToolDefinition`（每个工具*是什么*）。
其他一切都记录在**子页面**上，而非本页。划线的规则是：*你编写、持有或接收的类型是核心；为它提供类型推导、渲染或持久化的机制是子页面细节*。因此 `ToolDefinition` 是核心，但为它提供类型推导的 `ValueSchemaSpec`/`ParameterSchemaSpec` 机制、为它提供渲染意图的 `ToolCallView`/`ToolResultView` 词汇，以及存储事件日志的 `SessionPersistence` seam 都不是——它们分别在下列子页面中。
