chore(release): v1.5.1

Streaming robustness patch: block-memo now invalidates raw-HTML container
blocks while rehype-raw swallow is in effect (duplicate footnote section /
frozen trailing content fix), and the Mantine mermaid renderer follows an
explicit streaming lifecycle (silent mid-stream failures, generation reset
on regenerate, single corrective pass at stream end, body-path rendering
to survive hidden-host measurement). See docs/release-highlights.md.

 ## 1.5.x — Mantine 9
 
+### 1.5.1 — Streaming robustness: raw-HTML swallow and mermaid lifecycle
+
+- Core's block-memo cache no longer freezes stale content when a streaming document contains an unclosed raw-HTML container (`<details>` before its `</details>` arrives — but any container tag qualifies). rehype-raw's HTML parsing reparents every following sibling into the open container, including the synthetic footnote section, while the block's source-level cache identity stays byte-identical; the first swallowed snapshot used to become a permanent cache hit, leaving a duplicated footnote section trapped inside the container and freezing trailing content mid-stream. Raw-HTML blocks now carry a structural digest of their rendered subtree, so the cache invalidates exactly while swallowing is in effect and recovers in one frame once the close tag lands. Markdown-native blocks skip the digest walk entirely — no new per-frame cost on large deterministic subtrees like KaTeX output.
+- `@ai-react-markdown/mantine`'s mermaid renderer is now streaming-aware. While `streaming` is true, parse failures on truncated code are silent: the raw source shows as a plain code block until the first prefix parses, then the last good SVG stays up and refreshes on each subsequent success — no more "Mermaid Render Error" flashes mid-stream. When streaming ends, one corrective pass runs on the final code; its failure is the only one allowed to replace a rendered diagram. A `streaming` false→true edge is treated as a new generation (chat "regenerate" reuses the same component instance) and resets the warm-up state, so a new stream never shows the previous generation's stale diagram or error tab. Static (non-streaming) rendering keeps the original conservative rule: a rendered diagram is never clobbered by a later transient failure.
+- `mermaid.render` no longer receives the host element: the host is hidden during warm-up, and `display: none` zeroes mermaid's getBBox text measurement — one-shot static renders came out as ~16px SVGs. Rendering through mermaid's own body-temp path decouples measurement from container visibility; `suppressErrorRendering` additionally keeps mermaid's temp nodes from accumulating in `document.body` when a draw-phase error slips past `parse`.
+- Storybook gains a `Mantine/MantineAIMarkdown → Streaming` story that streams a mermaid-heavy document token by token; `content` is a control, so arbitrary markdown can be streamed for eyeballing.

 ### 1.5.0 — `@ai-react-markdown/mantine` moves to Mantine 9
 
 - `@ai-react-markdown/mantine` now requires `@mantine/core` and `@mantine/code-highlight` `^9.0.0` as peers (tested against 9.4.1). No API changes on our side — the package's surface survives every Mantine 9 breaking change untouched. Consumers inherit Mantine 9's defaults: `md` (8px) default radius, solid light-variant colors (Mantine's `v8CssVariablesResolver` restores the 8.x look), and a React 19.2 floor.
