* 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.

* fix(web): harden ContentViewer blob/CSV rendering per review (#1551)

Address review feedback on the ContentViewer MIME-dispatch PR:

- useObjectUrl: fix a dev-only StrictMode bug where the committed object
  URL was revoked but never recreated (setup→cleanup→setup with no
  re-render), blanking PDF/HTML previews. 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.
