Status icons added to developer integration sections

The documentation page outlines request quotas, concurrency constraints, and usage thresholds across developer tiers for the service API. In this revision, no numerical request allowances, token ceilings, or monetary thresholds were altered. Instead, navigation or table listings for several integration topics received updated status markers. Entries representing Model Context Protocol network connections, software extensions, extension catalogs, and automated routine execution each gained a new indicator symbol. Prior to the edit, routine triggers displayed no trailing symbols, while the other three integration categories each displayed a single marker. Following the modification, all four entries present an additional icon, bringing the total to two markers for the first three categories and one marker for routine triggers. In practice, operational quotas and rate allowances for active accounts remain completely unaffected by the update. The adjustment appears purely informational within the documentation layout. However, the raw text diff does not explain the exact meaning of these specific glyphs, such as whether they denote preview availability, authentication prerequisites, or feature deprecation, nor does it specify how quotas apply to those particular integrations.
