VS Code extension session history missing old sessions

[Insomnium1250]

Description

The VS Code extension's session history picker does not show previously created sessions from the same VS Code extension. Sessions created from the Claude Code desktop app are visible in the desktop app's history, but VS Code sessions are not visible in the VS Code extension's session picker.

Steps to Reproduce

1. Work in a VS Code Claude Code extension session for an extended period (e.g., 10+ hours)
2. Close the session
3. Open VS Code again and check session history
4. Old VS Code sessions do not appear in the picker

Observed Behavior

• Session history in VS Code extension does not show previously created VS Code sessions
• Sessions created via Claude Code desktop app appear correctly in the desktop app's history
• The session data does exist on disk at ~/.claude/projects/<project>/ with full .jsonl conversation logs

Expected Behavior

All sessions for the current project should appear in the VS Code extension's session history, regardless of which entrypoint (VS Code, desktop, CLI) created them.

Specific Example

Session 3ef9b200-77ce-452b-a08f-7275327d436c:

• Entrypoint: claude-vscode
• Created: 2026-04-13 11:23 — Last modified: 2026-04-13 22:37
• Size: 20MB .jsonl file
• Features used: remote control enabled
• Status: Data exists on disk, but does not appear in VS Code session picker

Update: Worktree involvement confirmed

Further investigation shows the missing session (3ef9b200) spawned a git worktree during the session:

• .jsonl conversation log stored in ~/.claude/projects/d--qmdj-app/
• subagents + tool-results stored in ~/.claude/projects/d--qmdj-app--claude-worktrees-dt-focus-inject/

The session started in the main project directory but created a worktree (d:\qmdj-app\.claude\worktrees\dt-focus-inject) during work. The VS Code extension session picker may be:

1. Looking at the worktree project path instead of the main project path, or
2. Not reconciling sessions that span both a main project and its worktrees

Active worktrees on this repo:

D:/qmdj-app                                           [master]
D:/qmdj-app/.claude/worktrees/dt-focus-inject         [worktree-dt-focus-inject]
D:/qmdj-app/.claude/worktrees/experiment+dt-focus-inject [worktree-experiment+dt-focus-inject]

This may not be a general session history bug but rather specific to sessions that use EnterWorktree during the conversation.
