Auto-link keywords, product names, and terminology within article text

[rvanmaanen]

Automatically detect and link keywords, product names, and glossary terms within rendered article content. Two categories of links:

• Product/technology keywords (e.g., "GPT-5-Codex", "GitHub Copilot", "Azure AI Foundry"): Link to a filtered content view showing all items tagged with or related to that keyword.
• Terminology/glossary terms (e.g., sections, collections, items as defined in docs/terminology.md): Link to the term's definition or show a tooltip/popover on hover.

Implementation considerations:

• Define a keyword-to-filter mapping (could reuse the existing tag system for products, a glossary data source for terminology).
• Implement as a markdown post-processing step in the content pipeline.
• Avoid over-linking: only link the first occurrence per article, skip headings, code blocks, and already-linked text.
• Link product keywords to the appropriate section/collection filtered by the relevant tag.
