feat(core): add markdown table rendering support

[Twisted928]

Credit to OpenCode and oh-my-opencode for the implementation.

Summary
Add markdown table rendering support to @opentui/core, enabling proper display of markdown tables in TUI applications with aligned columns and box-drawing borders.
Features

• Three rendering styles: Unicode (box-drawing), ASCII, and compact (no borders)
• CJK support: Correct character width calculation for Chinese, Japanese, Korean, and emoji
• Column alignment: Support for left, center, and right alignment via :---, :---:, ---:
• Configurable options: maxColumnWidth, minColumnWidth, cellPadding, style
  Example Output
  Input:
  | Name | Age | City |
  |:-----|:---:|-----:|
  | Alice | 30 | NYC |
  | 田中太郎 | 28 | 東京 |
  Unicode style output:
  ┌──────────┬─────┬──────┐
  │ Name │ Age │ City │
  ├──────────┼─────┼──────┤
  │ Alice │ 30 │ NYC │
  │ 田中太郎 │ 28 │ 東京 │
  └──────────┴─────┴──────┘

Usage

<code
  content={markdownContent}
  filetype="markdown"
  syntaxStyle={syntaxStyle}
  table={{ enabled: true, style: "unicode" }}
/>

@msmps Thanks for the heads up! I noticed that #433 might still have an issue with table column alignment - the table.align array from marked (which contains "left", "center", "right" from :---, :---:, ---: syntax) doesn't seem to be used in createTableRenderable.

Happy to contribute a fix for that if needed once #433 is merged.

@Twisted928 marked is used to render boxes, the layout is then done by Yoga. This way it even supports truncating cells that are too long. You can see a preview image in the PR
