Fix swallowed Tab after raw ANSI Shift+Tab in ted

[Copilot]

ted could suppress the first Tab after handling raw ANSI Shift+Tab (ESC [ Z), so re-indenting required pressing Tab twice. Existing key-injection tests missed this because they bypassed the raw ANSI parser path.

• Input state handling

  • Clear Terminal.Gui’s one-shot ANSI printable suppression after Editor handles Command.Unindent.
  • Scope the workaround to AnsiInputProcessor and make it a no-op if the internal TG field changes.

• Regression coverage

  • Added a raw ANSI ted integration test that exercises:

    Tab → Shift+Tab (ESC [ Z) → Tab
    

  • Verifies the first post-unindent Tab immediately inserts indentation.

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
