Fixes #2873
In the macro editor, the autocomplete suggestions in command mode ⟨\⟩ should be disabled.

Summary

Disabled the autocomplete popup suggestions in the macro editor while keeping the \ hybrid command mode functional.

Issue Found

When editing macros in the macro editor, typing \ would trigger the command mode ⟨\⟩ with a popup of autocomplete suggestions.

Changes

Modified src/Edit/Interface/edit_source.cpp:

// Disable autocomplete options in the macro editor
string buf_name= as_string (buf->buf->name);
if ((starts (buf_name, "tmfs://aux/edit-") &&
     buf_name != "tmfs://aux/edit-shortcuts" &&
     !starts (buf_name, "tmfs://aux/edit-comment")) ||
    buf_name == "tmfs://aux/macro-editor") {
  return;
}

How to test

1. Open Mogan Editor.
2. Open the macro editor via Tools → Macros → New macro or Edit macros.
3. Press the \ key and begin typing.
4. Verify:
   • The ⟨\⟩ bracketed tag (hybrid command mode) appears correctly.
   • No autocomplete suggestion popup appears while typing.
