fix: optimize visualization hot paths and refine bgp brief workspace

docs/CHANGELOG.md

 - Fixed [backend/app/api/v1/bgp.py](/home/ray/dev/linkong/planet/backend/app/api/v1/bgp.py) so `events`, `anomalies`, and `incidents` no longer fetch whole tables into Python just to apply filtering, pagination, and counting.
 - Fixed the repository workflow around saved BGP brief artifacts by ignoring [data/ai/bgp-briefs/](/home/ray/dev/linkong/planet/data/ai/bgp-briefs/) in [.gitignore](/home/ray/dev/linkong/planet/.gitignore) instead of leaving runtime Markdown output to pollute git status during normal operator use.
 
+## 0.24.6
+
+Released: 2026-04-10
+
+### Highlights
+
+- Tightened several backend hot paths outside the original BGP page fixes, stabilized BGP collector coverage after the recent query refactors, and rebuilt the BGP AI brief tab so saved Markdown briefs render and scroll like a proper operator workspace instead of collapsing inside the shared table layout.
+
+### Improved
+
+- Improved [backend/app/api/v1/datasources.py](/home/ray/dev/linkong/planet/backend/app/api/v1/datasources.py) by replacing per-datasource task, count, and endpoint lookups with batched prefetch helpers, reducing the worst `1 + N` behavior on the datasource list and `trigger-all` flow.
+- Improved [backend/app/api/v1/visualization.py](/home/ray/dev/linkong/planet/backend/app/api/v1/visualization.py) by switching the main Earth-facing `CollectedData` endpoints to `is_current` records, batching multi-source loads for aggregate endpoints, and removing stale Python-side dedupe paths from the hot route.
+- Improved [backend/app/services/bgp_incidents.py](/home/ray/dev/linkong/planet/backend/app/services/bgp_incidents.py) and [backend/app/services/bgp_enrichment.py](/home/ray/dev/linkong/planet/backend/app/services/bgp_enrichment.py) by avoiding historical full-table infrastructure scans, narrowing observation baseline payloads to required columns, and pushing more ASN filtering into the database.
+- Improved [backend/app/api/v1/alerts.py](/home/ray/dev/linkong/planet/backend/app/api/v1/alerts.py), [backend/app/api/v1/dashboard.py](/home/ray/dev/linkong/planet/backend/app/api/v1/dashboard.py), and [backend/app/api/v1/settings.py](/home/ray/dev/linkong/planet/backend/app/api/v1/settings.py) by collapsing several repeated count and settings queries into fewer aggregate or batched reads.
+- Improved [frontend/src/pages/BGP/BGP.tsx](/home/ray/dev/linkong/planet/frontend/src/pages/BGP/BGP.tsx), [frontend/src/index.css](/home/ray/dev/linkong/planet/frontend/src/index.css), and [frontend/src/components/MarkdownRenderer/MarkdownRenderer.tsx](/home/ray/dev/linkong/planet/frontend/src/components/MarkdownRenderer/MarkdownRenderer.tsx) by rebuilding the `AI 简报` tab layout, fixing saved brief scrolling behavior, and extending the renderer to handle tables, separators, and stored metadata comments more gracefully.
+- Improved [docs/ai-playground-development-plan.md](/home/ray/dev/linkong/planet/docs/ai-playground-development-plan.md) by explicitly recording that the current BGP brief is only the first-stage summary flow and that regional prefix-geography analysis remains a planned Phase B follow-up.
+
+### Fixed
+
+- Fixed [backend/app/services/bgp_collectors.py](/home/ray/dev/linkong/planet/backend/app/services/bgp_collectors.py) and [backend/app/services/bgp_enrichment.py](/home/ray/dev/linkong/planet/backend/app/services/bgp_enrichment.py) so JSON field extraction no longer depends on the less portable `.astext` path that could break BGP collector endpoints in local environments.
+- Fixed the BGP AI brief tab in [frontend/src/index.css](/home/ray/dev/linkong/planet/frontend/src/index.css) and [frontend/src/pages/BGP/BGP.tsx](/home/ray/dev/linkong/planet/frontend/src/pages/BGP/BGP.tsx) so long saved briefs are no longer compressed into a tiny clipped viewport by the shared tab/table overflow rules.
