Concise transcript mode drops reasoning rows regardless of showReasoning / ctrl+t #5426

Describe the bug

Version: Copilot CLI 1.0.110-1 (prerelease channel), macOS darwin-arm64
Model: claude-opus-5.5. Experimental mode on.
Flag: CONCISE_TRANSCRIPT enabled by rollout (I didn't set it)

Expected: A collapsed "Thinking…" / "Thought for Ns" row I can click to expand (showReasoning=false), or expanded reasoning (showReasoning=true).

Actual: No reasoning row appears in either setting, and ctrl+t changes nothing. Reasoning is still received: assistant.message events in events.jsonl contain reasoningText. Setting enabledFeatureFlags.CONCISE_TRANSCRIPT=false brings the rows back.

Cause (1.0.110-1 cli-main.js, minified): the concise transform (yur) skips reasoning entries unconditionally. It ends with a.type!=="reasoning"&&(s(!0),n.push(...)), with no showReasoning check.

Affected version

1.0.110-1

Steps to reproduce the behavior

1. With CONCISE_TRANSCRIPT on, set "showReasoning": false (or true).
2. Prompt a reasoning model with something that makes it think, then run a tool.
3. Press ctrl+t to toggle reasoning display.
