baf79b843f* feat(web): expand ContentViewer to render PDF, CSV, HTML, XML, JSON, CSS (closes #1329) Turn ContentViewer into a per-MIME dispatch surface for resource content. It now accepts raw TextResourceContents | BlobResourceContents (in addition to the existing ContentBlock path), so ResourcePreviewPanel.toContentBlock collapses to a passthrough and blob-typed resources render natively instead of falling back to opaque "[Binary content …]" text. New renderers (clients/web/src/components/elements/): - CodeHighlight: lazy react-syntax-highlighter prism-light element. Runtime, tomorrow theme, and each grammar dynamic-import on first use (one chunk per grammar). Module-level registeredLanguages / failedLoads / loadingPromises caches; plain Code block until a grammar resolves. - PdfFrame: iframe over a Blob URL (#view=FitH), revoked on unmount. - CsvTable: papaparse -> Mantine Table (first 100 rows), plain-Code fallback. - HtmlFrame: sandbox="" iframe over a Blob URL with an injected CSP meta (no script-src, falls through to default-src 'none'). - contentViewerUtils: getMimeKind, base64 decode helpers, formatXml, wrapHtmlWithCsp, SAFE_HREF markdown-anchor allowlist (unsafe href -> span). ResourcePreviewPanel: extend the URI-suffix MIME inference table (.csv/.json/.xml/.html/.htm/.css/.pdf alongside .md). Deps: papaparse + react-syntax-highlighter (+ @types). tsconfig paths stubs redirect the deep RSH imports for typecheck (the @types ambient declarations are shadowed by the real .js under bundler resolution) — same pattern the repo uses for react/pino. Tests cover PDF blob-URL creation + cleanup, CSV table render + fallback, HTML sandbox attributes + CSP injection, JSON/XML/CSS highlighted output, the lazy-load/alias/failed-load/shared-runtime paths, and the URI-suffix MIME-inference paths. validate, test:coverage (per-file gate), test:storybook, and integration all pass.

Revocation is now deferred to a microtask and guarded by a "live URL" ref so a StrictMode re-setup cancels it, while a real unmount / blob change still releases the URL. Avoids set-state-in-effect; mirrors AppRenderer's deferred-disposal. - atob: guard base64 decoding with tryDecodeBase64ToUtf8 / tryDecodeBase64ToBytes so a malformed blob from an external server degrades to the binary-content notice instead of throwing during render and taking down the whole preview panel. - CsvTable: surface the 100-row display cap with a "Showing first N of M rows" caption (no silent truncation). - Extract BinaryNotice into its own module so PdfFrame can reuse it without an import cycle. Tests added for the StrictMode path, malformed-base64 fallbacks (PDF + textual blob), the safe-decode helpers, and the truncation caption.
