Auto-context file chip (from autoIncludeOpenedFiles) no longer shown in input bar since v2.1.220

Title: Auto-context file chip (from autoIncludeOpenedFiles) no longer shown in input bar since v2.1.220

Description:

Since updating the Claude Code VS Code extension to v2.1.220, the automatic file-context chip that used to appear next to the + / / icons in the chat input bar — showing the name of the file currently opened/selected in the editor — no longer appears.

Expected behavior (confirmed working in v2.1.199, released 2026-07-02):
When a file is opened or a selection is made in the editor, a chip with the file name (e.g. README.md) is shown above/next to the input bar, confirming that this file's context is included automatically.

Actual behavior (v2.1.220, released 2026-07-25):
No chip appears for the auto-included open/focused file, even though the setting claudeCode.autoIncludeOpenedFiles is still set to true.

Steps to reproduce:

1. Set "claudeCode.autoIncludeOpenedFiles": true in settings.json.
2. Open any file in the editor / select some text.
3. Observe the chat input bar area next to the + and / icons.

• v2.1.199: file chip appears.
• v2.1.220: no chip appears.

Environment:

• OS: Windows 11 Pro 10.0.26200
• Extension: anthropic.claude-code
• Broken version: 2.1.220
• Last known working version: 2.1.199

Why this matters:
The manual @-mention file picker still works fine and is a useful additive way to add context explicitly. However, the automatic focus/open-file indicator is a different and important mechanism: it gives immediate visual confirmation of which file's context is implicitly included based on editor focus, without requiring a manual @ action every time. Losing this makes it unclear whether the currently open/selected file is actually being included in context, which was a key part of the daily workflow.
