pi-openai-fast-mode

Pi package that adds a Fast Mode toggle for GPT-5.6, GPT-5.5, and GPT-5.4.

Features

• Registers /fast [on|off|toggle].
• Registers --fast to enable Fast Mode at startup.
• Injects service_tier: "priority" into matching OpenAI/OpenAI-Codex provider payloads.
• Shows a compact right-aligned TUI fast indicator only when enabled and the current model is configured.
• Persists state in user or project scope depending on how the package is loaded.
