chore(release): SDK 定版 1.1.0（1.1.x 线全程共用）

按 核心仓 docs/git-branching.md §七.1，SDK 版本跟随核心的中版本、
patch 位恒为 .0：整条核心 1.1.x 线（1.1.0、1.1.1、…、1.1.N）共用 SDK 1.1.0。

**为什么不跟着核心 patch 走**：SDK 版本号是插件开发者的依赖声明。核心的 patch
专用于 bugfix 与漏洞修复，不碰公开接口；若每个 bugfix 都推一个 SDK 新号，
开发者要么被迫跟版、要么怀疑自己版本过时，而接口一个字都没变。

本版内容见 tag v1.1.0 的发布说明。

+与 `SetToolBlocks` 的区别：`SetToolBlocks` 只能在工具处理函数内部调用，媒体要等到
+下一条 tool message 才到模型手上；这三个方法是插件**主动发起一轮带媒体的对话**，
+媒体在本轮就随消息发给模型，并自动落进媒体存储、挂上媒体记忆引用。
+
+媒体块里的 `data:` URL 会被内核落盘去重；`http(s)` URL 只透传给模型，不入库
+（入库需要内核发起网络请求，涉及超时、鉴权与 SSRF）。

+### 记忆里的媒体（1.1.0 新增）
+
+媒体在纯文本记忆里以**标记**形式存在，格式 `[<mime> <短digest>] <描述>`：
+
+```
+[image/png a1b2c3d4e5f6] 一张紫蓝红三色带图
+```
+
+描述文本是持久的语义记忆（检索靠它），digest 是回到字节的钥匙（反查靠它）。
+标记由内核生成，插件不必自己拼——**填 digest 就够**。
+
+#### 图记忆
+
+```go
+s.Memory().Commit([]sdk.Triple{{
+    Subject: "配色图", Relation: "包含", Object: "三色带",
+    MediaDigests: []string{"a1b2c3d4e5f6"}, // 短 digest 即可，内核补全

+})
+```
+
+`Insert` 保持原签名不变，正文里已有的标记同样会被挂成文档级引用。
+`Query` 返回的 `Doc` 带 `MediaDigests` 与 `Attachments`（mime + 描述，
+**不含字节**——一次检索可能命中几十份媒体）。删除文档时引用自动释放。
+

+    Role: "user", Content: "看这张图",
+    Attachments: []sdk.MediaAttachment{{MIME: "image/png", Data: pngBytes}},
+})
+```
+
+`RecentEvents` 读回时正文里的标记会被反解成 `Attachments`。
+
+媒体存储可在内核侧关闭（`core.memory.media.enabled=false`），此时以上接口
+全部退化为纯文本行为：不报错、不 panic，与本特性上线前一致。

+
+| Method | Description |
+|--------|-------------|
+| `InjectInputMedia(source, channel, text, blocks)` | Inject media-bearing input, asynchronous |
+| `InjectInputMediaSync(source, channel, text, blocks)` | Inject media-bearing input and wait for the reply text |
+| `InjectInterruptMedia(source, channel, text, blocks)` | Inject a media-bearing interrupt that can preempt current processing |

+
+```go
+s.InjectInputMedia("myplugin", "webui", "take a look at this", []sdk.ContentBlock{{
+    Type:     "image_url",
+    ImageURL: &sdk.ImageURL{URL: "data:image/png;base64," + b64, Detail: "auto"},
+}})
+```
+
+How this differs from `SetToolBlocks`: that one is only callable inside a tool handler and
+its media reaches the model with the *next* tool message. These three let a plugin
+**initiate a turn that carries media** — the media goes out with this turn's message and is
+automatically stored in the media store with a memory reference attached.
+
+`data:` URLs in the blocks are stored and deduplicated by the kernel; `http(s)` URLs are
+passed to the model only and never stored (storing them would require the kernel to make
+network requests, bringing timeouts, auth and SSRF into scope).
+
 `source` identifies the origin, `channel` specifies the target output channel.
 
 ### Triple Extended Fields

 - `Confidence` — confidence score (0.0–1.0)
 - `SubjectType` — subject type
 - `ObjectType` — object type
+- `SentenceText` — the original sentence (added in 1.1.0), written to the `sentences` table; media references hang off the sentence
+- `MediaDigests` — associated media digests (added in 1.1.0)
+
+### Media in Memory (added in 1.1.0)
+
+Inside plain-text memory, media is represented as a **marker** of the form
+`[<mime> <short digest>] <description>`:
+
+```
+[image/png a1b2c3d4e5f6] a purple-blue-red three-band chart
+```
+
+The description is the durable semantic memory (retrieval uses it); the digest is the key
+back to the bytes (reverse lookup uses it). Markers are generated by the kernel — a plugin
+never has to assemble one, it just **supplies the digest**.
+
+#### Graph memory
+
+```go
+s.Memory().Commit([]sdk.Triple{{
+    Subject: "palette", Relation: "contains", Object: "three-band",
+    MediaDigests: []string{"a1b2c3d4e5f6"}, // short digest is fine, the kernel resolves it
+}})
+```
+
+With no `SentenceText`, the kernel uses the marker itself as the sentence — media must have
+a sentence to hang off, otherwise the reference has nowhere to attach.
+
+#### Knowledge base
+
+```go
+s.DocMemory().InsertWithMedia(&sdk.Doc{
+    Title:   "illustrated note",
+    Content: "body",
+}, []sdk.MediaAttachment{
+    {MIME: "image/png", Data: pngBytes, Name: "chart.png"}, // new content, stored and deduped
+    {Digest: "a1b2c3d4e5f6"},                               // reference existing content
+})
+```
+
+`Insert` keeps its original signature; markers already present in the body are bound as
+document-level references too. `Query` fills `MediaDigests` and `Attachments` (mime plus
+description, **no bytes** — one query can match dozens of media items). Removing a document
+releases its references.
+
+#### Text memory
+
+```go
+s.TextMemory().Append(sdk.TextEvent{
+    Role: "user", Content: "look at this",
+    Attachments: []sdk.MediaAttachment{{MIME: "image/png", Data: pngBytes}},
+})
+```
+
+`RecentEvents` decodes markers in the body back into `Attachments`.
+
+The media store can be disabled kernel-side (`core.memory.media.enabled=false`); all of the
+above then degrades to plain-text behaviour — no errors, no panics, identical to how it
+behaved before this feature shipped.
