Option to use chatgpt tools such as web search via API

[lfinbob]

It would be great if chatgpt-cli supported usage of chatgpt tools, such as web search, directly in config.yaml
That way we can get a more ChatGPT-like experience (e.g., web browsing).

Proposed behavior:

• Allow specifying tools such as web search in config.yaml

• When tools are defined, chatgpt-cli should:

  • Include them in each API call (e.g., tools: [...] and tool_choice: "auto")
  • Allow overriding/enabling tools per-invocation via flags (optional nice-to-have)

Motivation:

• The web UI already integrates tools like web browsing automatically.
• Being able to define tools in config.yaml would let CLI users opt in to similar functionality

Thanks for considering this feature!
