[Bug] OSC 8 hyperlink labels are not clickable #869

Description

When markdown concealment is enabled, a markdown link like:

[opentui#866](https://github.com/anomalyco/opentui/pull/866)

renders visually as:

opentui#866 (https://github.com/anomalyco/opentui/pull/866)

But in Windows Terminal with PowerShell, only the visible URL suffix is clickable. The visible label text opentui#866 is not clickable.

Expected behavior

With concealment enabled, the visible label text should carry the same OSC 8 hyperlink metadata as the link target, so the user can Ctrl+Click the label itself. The clickable region should include the rendered link label, not only the visible URL suffix.

Actual behavior

Only the rendered URL portion is clickable:

• Not clickable: opentui#866
• Clickable: (https://github.com/anomalyco/opentui/pull/866)

Environment

• OpenCode: 1.3.0
• @opentui/core: 0.1.90
• OS: Windows 11
• Terminal: Windows Terminal
• Shell: PowerShell 7.6.0

Reproduction

Render a markdown link in a concealed markdown block, for example:

[opentui#866](https://github.com/anomalyco/opentui/pull/866)

Observe that:

• the label is shown
• the URL suffix is shown
• Ctrl+Click works on the URL suffix
• Ctrl+Click does not work on the label

Analysis

This appears to be specific to the concealed markdown rendering path:

• opentui#607 added link: { url } metadata in the markdown token/chunk path
• normal markdown paragraphs are now rendered through CodeRenderable(filetype="markdown")
• with conceal=true, the visible label is produced by the tree-sitter conceal/render path
• the visible URL suffix is linkified separately
• result: the URL cells get OSC 8 metadata, but the concealed label cells do not
