Include thinking/reasoning logs in shared context (Gist, clipboard, HTML export)

[kianhub]

Problem

When sharing conversation context via Publish as GitHub Gist, Copy Context, or other export methods, thinking/reasoning logs are silently stripped out. The formatLogsForClipboard() function in src/renderer/utils/contextExtractor.ts (line 667) explicitly filters to only user, ai, and stdout sources — excluding thinking, tool, system, stderr, and error entries.

This means shared conversations are missing potentially valuable reasoning context. When a user shares a conversation to show how an agent arrived at a solution (not just the final output), the thinking logs are essential.

Note: HTML export (generateTabExportHtml in src/renderer/utils/tabExport.ts) already includes thinking logs — this inconsistency makes the gap more noticeable.

Proposed Solution

Add an "Include thinking/reasoning" toggle to the context sharing flow. When enabled, thinking blocks are included in the exported content.

Affected export paths

Export method	Current behavior	Proposed
Copy Context (clipboard)	Thinking excluded	Opt-in toggle
Publish as GitHub Gist	Thinking excluded	Opt-in toggle in GistPublishModal
HTML Export	Thinking already included	No change needed

Implementation notes

• formatLogsForClipboard() (src/renderer/utils/contextExtractor.ts:667) — Add an optional includeThinking?: boolean parameter. When true, include source: 'thinking' entries, formatted with a clear THINKING: header to distinguish them from assistant responses.
• GistPublishModal.tsx — Add a checkbox/toggle: "Include reasoning/thinking logs". Pass the flag through to formatLogsForClipboard() via the export handler.
• useTabExportHandlers.ts — handleCopyContext() and handlePublishTabGist() both use formatLogsForClipboard(). Both should respect the toggle. For clipboard copy (which has no modal), consider either a settings-level preference or a secondary menu option.
• Formatting — Thinking blocks should be visually distinct in the markdown output (e.g., wrapped in a <details> tag or prefixed with THINKING:) so they don't get confused with assistant responses.

UX considerations

• Default should be off (current behavior preserved) — thinking logs can be verbose and many users won't want them in shared gists.
• The toggle should be per-export, not a global setting, since the same user may want thinking in some shares but not others.
• Consider also including tool source entries as an additional option, since tool calls (file reads, searches, etc.) provide important context for understanding the conversation flow.
