fix(fs): correct Note pre-release link and restore read.ts decline coverage

The Note's pre-release-stance link used the wrong depth and target
(../../../CLAUDE.md); point it at ../../../../AGENTS.md with the section
anchor so verify-md-links passes. The presentResult decline test's meta
lacked the now-required offset, so it declined at meta narrowing instead of
exercising the content-shape decline (read.ts:181-183); add offset back.

The read tool projects the structured window through `output.presentationMeta`, the same persisted channel write/edit use for their applied-diff hunks ([canonical tool output contract](../architecture/2026-07-20-canonical-tool-output-contract.md)). `presentationMeta` runs once for a top-level surface call, returns `{ path, offset, lines, totalLines, lang? }` as JSON the session validates and stores on the result's `meta`, and `presentResult` narrows that meta back into the `ReadResultView` on both live and replay paths. `offset` (the 1-based first line the window requested) rides along because a byte cap below the first selected line yields an empty `lines` array with a positive `totalLines`; without the persisted `offset` a replayed card of such a window could not report where it starts or where a continuation resumes, and the last-line and re-parse fallbacks are both lossy. Without this channel the line array and total would be unreachable: the raw output object is not on the wire, and re-parsing the `N: text` text is lossy and fragile against the truncation footer.
`presentResult` returns `undefined` — the generic fallback — whenever the meta is absent or malformed (`readMetaFromMeta` narrows it defensively, so a replay of an older logged result never throws), whenever the result is an error, and whenever the single text block is not the read envelope. A pre-card logged result — a valid read envelope with no persisted `meta`, recorded before this card existed — takes that same `undefined` path deliberately: the client falls back to the raw `result.content`, so it shows the enveloped `<path>/<type>/<content>` text rather than the envelope-stripped generic card the old presenter returned. This is the accepted degradation under the [pre-release stance](../../../CLAUDE.md): reject the old on-disk format rather than add an envelope-stripping compatibility branch, since this PR re-records every published fixture and the session format promises no backward compatibility. On the success path `presentResult` carries `content` (the envelope-stripped text) alongside the structured fields, so a UI without the read capability, including the current TUI, renders the file text through the generic/default card arm exactly as before. The TUI's `renderBody` switch (`packages/ui/tui/src/components/transcript.ts`) is not `assertNever`-exhaustive: `terminal` and `diff` have arms and everything else falls through to the generic arm, which reads `view.content`. That default arm alone was not enough: `render()` sets `genericContent` — and with it the dim-Markdown `dimBody` treatment — on a separate gate that was `card === 'generic'` only, so a `read` card would have kept the text but lost its dim styling. The gate now admits `card: 'read'` too, taking `content` down the same dim-Markdown path, so a read renders in the TUI exactly as it did before the read card existed. Beyond that one gate the TUI needs no read-specific code.

read 工具通过 `output.presentationMeta` 投影结构化窗口,这与 write/edit 用来投影其应用 diff hunk 的持久化通道相同([规范化工具输出契约](../architecture/2026-07-20-canonical-tool-output-contract.md))。`presentationMeta` 对一次顶层 surface 调用运行一次,返回 `{ path, offset, lines, totalLines, lang? }` 作为会话校验并存储在结果 `meta` 上的 JSON`presentResult` 在 live 和回放路径上都把该 meta 收窄回 `ReadResultView``offset`(窗口请求的 1-based 起始行)一并携带,是因为当字节上限低于首个选中行时,窗口会返回空的 `lines` 数组而 `totalLines` 为正;没有持久化的 `offset`,这类窗口的回放 card 就无法报告它从哪行开始、或续读应从哪行继续,而末行推断与文本重解析两种兜底都有损。没有这个通道,行数组和总数就无法触及:原始输出对象不在线上,而重新解析 `N: text` 文本既有损又对截断脚注脆弱。
`presentResult` 在以下情况返回 `undefined`——即 generic 回退meta 缺失或畸形(`readMetaFromMeta` 防御性收窄它,因此回放旧的已记录结果永不抛错)、结果是错误、以及单个文本块不是 read 信封。本 card 出现之前记录的结果——信封合法但无持久化 `meta`——有意走同一条 `undefined` 路径:客户端回退到原始 `result.content`,因此显示带 `<path>/<type>/<content>` 信封的原文,而非旧展示器返回的剥信封 generic card。这是 [pre-release 立场](../../../CLAUDE.md)下接受的降级:拒绝旧的磁盘格式,而非加一个剥信封的兼容分支——本 PR 已重录全部已发布 fixtures且 session 格式不承诺向后兼容。在成功路径上,`presentResult` 在结构化字段之外携带 `content`(剥信封后的文本),因此不具备 read 能力的 UI包括当前的 TUI通过 generic/default card 分支渲染文件文本与之前完全一致。TUI 的 `renderBody` switch`packages/ui/tui/src/components/transcript.ts`)不是 `assertNever` 穷尽的:`terminal``diff` 有分支,其余都落入 generic 分支,该分支读取 `view.content`。仅有该默认分支还不够:`render()` 在一个独立门控上设置 `genericContent`(连同 dim-Markdown 的 `dimBody` 处理),该门控原先只判 `card === 'generic'`,因此 `read` card 虽保留文本却会丢失 dim 样式。现在该门控也接纳 `card: 'read'`,让 `content` 走同一条 dim-Markdown 路径,因此 read 在 TUI 中的渲染与 read card 出现之前完全一致。除这一处门控外TUI 无需 read 专属代码。
