🤖 Aspire triage pass — 2026-05-20 06:41 UTC

Area: area-dashboard
Kind: bug
Repro: yes-minimal — see the "REPRO STEPS" section of the issue body
Affected version(s): 13.4 (daily channel; new "AI Agents" feature)
Severity: S3 — localization gap on a new dashboard surface (English strings shown when UI language is Chinese); no functional break

Urgency: 🟡 vNext — recommend milestone 13.4
Reason: localization gap in a new 13.4 dashboard feature (AI Agents dialog + header tooltip); should be fixed before 13.4 GA but is not a 13.3.x shipping-bits regression.
