<!-- [DEF:TaskLogViewer:Component] -->
<!--
@TIER: CRITICAL
@SEMANTICS: task, log, viewer, inline, realtime
@PURPOSE: Displays task logs inline (in drawer) or as modal. Merges real-time WebSocket logs with polled historical logs.
@LAYER: UI
@RELATION: USES -> frontend/src/services/taskService.js
@RELATION: USES -> frontend/src/components/tasks/TaskLogPanel.svelte
@INVARIANT: Real-time logs are always appended without duplicates.

/**
* @TIER CRITICAL
* @PURPOSE Displays detailed logs for a specific task inline or in a modal using TaskLogPanel.
* @UX_STATE Loading -> Shows spinner/text while fetching initial logs
* @UX_STATE Streaming -> Displays logs with auto-scroll, real-time appending
* @UX_STATE Error -> Shows error message with recovery option
* @UX_FEEDBACK Auto-scroll keeps newest logs visible
* @UX_RECOVERY Refresh button re-fetches logs from API
