fix: enable infoset and infoset-diff views from any file context during debugging

[social5h3ll]

Fixes: #1703

Problem

While parsing a file, the Daffodil helper tab does not list the option to open the Infoset or Infoset Diff View unless the active tab is the DFDL schema file. This is because the infoset.display and infoset.diff commands are gated by editorLangId == 'dfdl' — they only appear when a DFDL schema file is the active editor.

This means if a user is debugging and switches to a data file or any other file type, they cannot access the infoset views from the Daffodil helper.

Root Cause

In package.json, the command enablement and menu when clauses both included editorLangId == 'dfdl':

"enablement": "inDebugMode && editorLangId == 'dfdl'"
"when": "inDebugMode && editorLangId == 'dfdl'"

This condition restricts the infoset commands to DFDL schema editors only, even though the infoset data is available throughout the debug session.

Fix

Remove && editorLangId == 'dfdl' from both the enablement field and the editor/title menu when clause for both infoset.display and infoset.diff commands.

After the fix:

• enablement: inDebugMode
• when: inDebugMode

This keeps the commands available only during active debug sessions but removes the schema-file-only restriction, so users can open the infoset views from any file context while debugging.

Acceptance Criteria

• Infoset view command available from Daffodil helper during debugging regardless of active file type
• Infoset diff view command available from Daffodil helper during debugging regardless of active file type
• Commands remain gated by inDebugMode (not available outside debug sessions)

Closes #1703
