[Desktop] Token counts no longer shown for tasks/subagents and during compaction

Environment: Claude desktop app (Code tab), macOS (Darwin 25.6), bundled Claude Code 2.1.286, Opus 5.5.

Description: Token consumption per task used to be visible in the Code tab of the desktop app. It no longer appears: neither for launched tasks/subagents nor during compaction, where the indicator only shows "Compacting session 12s" with no token count.

The CLI shows tokens in both places (2.1.257: live subagent token counters; 2.1.281: workflow row shows total tokens; 2.1.283: compaction spinner counts the summary's tokens), so the desktop UI seems to have lost this information. No changelog entry mentions a removal.

Expected: per-task token count (and compaction token count) displayed in the desktop app, as in the CLI.
