[dashboard DDX-11] Logs panel

[rickylabs]

Part of #400 · Part of #301

Handle: DDX-11 · Milestone: 0.0.1-beta.6 · Dep: DDX-5, DDX-3; browser-logs → DDX-1.

Scope — Logs panel

Acceptance

• Live structured logs (/api/telemetry/logs?follow=true NDJSON) + Aspire browser-log capture (withBrowserLogs, devtools: enable Aspire browser-logs integration by default (capture island/browser console in the dashboard) #218); filter by resource/severity. Prefer single multiplexed stream (HTTP/1.1 6-conn ceiling).

Design source: design/A-dashboard/epic-and-issues.md (DDX-11).

Dependency edge (DAG second pass): Depends on #415 (DDX-5), #413 (DDX-3).

Killed by the beta.6 rescope. Structured/console logs + ?follow NDJSON + level filters + withBrowserLogs capture are Aspire-native. ns-log-stream survives only as a correlated read-only strip inside Run Inspector (#419) that deep-links to Aspire structured logs ({aspireBase}/structuredlogs?resource={name}). No owned logs screen ships. Closing as superseded.
