  "message": "fix(frontend): virtualize dataset version file tree (#6285)\n\n### What changes were proposed in this PR?\n\nThis PR fixes the frontend issue where opening a dataset whose selected\nversion contains hundreds of files freezes the frontend for tens of\nseconds to minutes.\n\nRoot cause: the version file tree renders every file as a full tree-node\ncomponent (`@ali-hm/angular-tree-component` with virtualization\ndisabled), and each row\u0027s `nz-button` re-reads layout after every\nchange-detection pass.\n\nMeasured on the local dev stack (`ng serve`, Chrome, Long Tasks API),\ndatasets of N one-byte files:\n\n| N files | Page usable after (before → after) | Main thread blocked\n(before → after) | DOM rows (before → after) |\n|---|---|---|---|\n| 400 | 24.5 s → 1.3 s | 22.2 s → 0.2 s | 400 → 28 |\n\n### Any related issues, documentation, discussions?\n\nCloses #6281. Related to #5586 (same unbounded-rendering pattern in the\nupload lists).\n\n### How was this PR tested?\n\n\nhttps://github.com/user-attachments/assets/702b6ffa-7ac3-479e-9ac0-f1f186aa4739\n\n### Was this PR authored or co-authored using generative AI tooling?\n\nGenerated-by: Claude Code, Claude Fable 5",
