Subject: [PATCH] feat(feishu): render markdown tables as JSON 2.0 cards

Feishu's post-type 'md' elements do not support markdown tables,
causing table content to render as ugly plain text with pipe characters.

This change detects markdown table content and sends it as an
interactive card with schema 2.0, which natively renders tables
with proper borders, alignment, and pagination (max 5 data rows).

The card format is:
{
  schema: '2.0',
  body: { elements: [{ tag: 'markdown', content: ... }] }
}
