feat(web): shiki syntax highlighting for code surfaces

One highlighter for the client: a synchronous fine-grained shiki core
(JS regex engine, no WASM) in ui-primitives with an explicit grammar
allowlist (typescript, shellscript, json — aliases resolve, unknown
languages take a geometry-identical plain arm). The shared CodeBlock
component owns both arms; markdown fences, the run_code expanded
program body (typescript), and the details panel Input (json) all
route through it. Token colors live in a new ui-theme shiki.css sheet
as --shiki-* custom properties (light/dark blocks), wired through the
shell's base.css chain — tokens-only styling holds; shiki's generated
span tree is the sanctioned innerHTML path (static output, no user
HTML). jsdom specs pin token spans, aliases, both fallbacks, and the
fence route; the built-bundle snapshot asserts the highlighted program
under the code row.

+# Agent Note: Web client syntax highlighting — synchronous fine-grained shiki
+
+Status: implemented
+
+English | [中文](2026-07-26-web-syntax-highlighting-shiki.zh.md)
+
+> Scope: the web client's one syntax-highlighting system — the dependency ruling, the singleton shape, the token-sheet contract, and the consuming surfaces. Fifth PR of the Code Mode UI stack; the [chat sub-call rows note](../feature/2026-07-26-code-mode-chat-subcall-rows.md) shipped the `run_code` program body this exists to make readable. Styling ground rules are owned by [the web styling ruling](2026-07-19-web-styling-system.md).
+
+## Problem
+
+The client rendered every code surface — markdown fences in assistant prose, the `run_code` program body, the details panel's args — as flat monospace text. The stack's primary payload is model-written TypeScript; unhighlighted programs are measurably harder to scan, and the repo already ships shiki-highlighted code on its VitePress site, so the web app was the one code-rendering surface without it.
+
+## Decision
+
+**Shiki in its synchronous fine-grained form, as one `ui-primitives` singleton, themed exclusively through CSS custom properties.**
+
+- **Dependency**: `shiki/core` + `@shikijs/langs`, composed via `createHighlighterCoreSync` with `createJavaScriptRegexEngine({ forgiving: true })` — no oniguruma WASM, no async init, bundle-friendly. Grammar allowlist: `typescript` (embeds JS), `shellscript`, `json` — the languages the harness actually renders; everything else falls back to a geometry-identical plain block, never an error. Prior art: the VitePress site already renders all documentation code through shiki, and TextMate grammars materially beat regex highlighters on TypeScript — the payload that matters here.
+- **Singleton**: `ui-primitives/src/markdown/highlight.ts` lazily creates one `HighlighterCore` per document and exposes `highlightToHtml(code, lang)` (undefined = render plain). The shared `CodeBlock` component owns both arms; its shiki arm injects the generated span tree via `dangerouslySetInnerHTML` — sanctioned because shiki emits a static span tree computed from the code text (no user HTML passes through, no scripts/handlers), shiki's own documented consumption path.
+- **Theming**: shiki's `createCssVariablesTheme` routes every token color through `--shiki-*` custom properties; the VALUES live in a new `ui-theme/styles/shiki.css` token sheet (light on `:root`, dark on `body[data-ds-dark-theme]` — the same cascade as every other sheet), imported by the shell's `base.css` chain. Component CSS stays tokens-only; no literal color ever enters JS or component sheets. Background/foreground alias the existing markdown code-block tokens so highlighted and plain blocks agree.
+- **Surfaces**: markdown fences (`MarkdownText`'s `pre` component routes single-string fences through `CodeBlock`), the `run_code` expanded program body (ToolRow's code variant, `lang="typescript"`), and the details panel's Input args (`lang="json"`). Output stays plain deliberately — tool output is arbitrary text, and guessing a grammar would mis-highlight more than it helps.
+
+## Alternatives considered
+
+**`rehype-highlight`/lowlight.** Runner-up: naturally sync and ~⅓ the bundle, but regex-grammar fidelity on TypeScript is visibly worse, and the repo would then run two highlighter systems (site: shiki, app: highlight.js) with two theming vocabularies.
+
+**Full `shiki` bundle or the oniguruma WASM engine.** Rejected: the full bundle ships every grammar/theme; WASM needs async loading the sync client boot deliberately avoids. The fine-grained core with three grammars keeps the cost proportional to actual use.
+
+**Highlight in a worker / async.** Rejected: the payloads are small (programs, fences, args); the synchronous JS engine tokenizes them in microseconds, and async introduces a flash-of-unhighlighted-code plus render-machinery churn for no measured need.
+
+## Consequences
+
+One code surface for every consumer — a future surface imports `CodeBlock` and inherits highlighting, theming, and the plain fallback. The bundle grows by the shiki core + three grammars (paid once in `ui-primitives`). Token colors are the first `--shiki-*` sheet; a theme package registering alias overrides extends them like any other token. jsdom specs pin the token-span structure, alias resolution, both fallback arms, and the fence route; the existing built-bundle snapshot and browser e2e cover the assembled path.
