#3335: Increase default markdown preview size limits (64KB / 1500 lines too restrictive)

We'll provision a sandbox, run an agent against the issue, and open a draft PR. You can pull the branch and iterate from there.

The current defaults for rich markdown preview in the workspace panel are:

  • MD_PREVIEW_RICH_RENDER_MAX_BYTES = 64 * 1024 (64 KB)
  • MD_PREVIEW_RICH_RENDER_MAX_LINES = 1500

Files slightly above these thresholds (e.g. 85 KB / 2549 lines) fall back to plain text with no option to force-render. Suggested defaults: 256 KB / 5000 lines, or alternatively expose these as environment variables (e.g. HERMES_WEBUI_MD_PREVIEW_MAX_BYTES) so users can tune them without patching the source.
