[FEATURE]: multi-account OpenAI support — account pool, /account commands, interactive picker

[lNimien]

Feature hasn't been suggested before.

• I have verified this feature I'm about to request hasn't been suggested before.

Describe the enhancement you want to request

Context

I'm aware of previous requests for this feature (#8591, #9068, #11830)
but none received maintainer feedback. I'm opening this one because
I have a working implementation ready.

Problem

Currently, /connect overwrites the previous OpenAI account every time it's used.
There is no way to have multiple ChatGPT accounts connected simultaneously.
This is a significant limitation for users who manage several accounts and want to
distribute usage across them without manually reconnecting every time.

Scope

This implementation is OpenAI-only — specifically for users running
ChatGPT Plus with Codex quota. No generic multi-provider abstraction,
no over-engineering. Just the problem I actually had.

Proposed Solution

We implemented a multi-account pool for OpenAI in a fork. The approach is minimal,
backwards compatible, and OpenAI-specific (no over-engineered generic abstraction).

What We Built

• /connect now accumulates accounts instead of overwriting — each new login adds
  a new entry to the pool
• /account list — shows all connected accounts with email and status (enabled/disabled/active)
• /account use — interactive picker with arrow keys + Enter to switch active account
• /account disable — interactive picker to disable an account from the pool
• /account remove — interactive picker to remove an account from the pool
• Visual indicator in the TUI showing the active account email next to the model indicator
• Full backwards compatibility with existing single-account auth.json format —
  existing users are not affected

Technical Approach

• Extended auth.json with an accounts[] array under the OpenAI key
• Old single-account format is auto-migrated on first read
• /account commands are local TUI commands, not model prompts
• Token refresh updates only the selected account entry, never touches others
• New backend endpoints: GET/DELETE/POST /provider/openai/account/...

Status

We have a working fork validated on Windows 11. All features above are functional.

Question for Maintainers

Would you be interested in a PR for this? If so, do you have preferences on:

• The storage approach (auth.json extension vs separate file)
• Whether session affinity (pinning a session to a specific account) should be
  included in the same PR or as a follow-up
• Any specific test coverage requirements

Happy to polish and submit a proper PR if there's interest.

I was using this on version 1.14.50, so my branch already has it merged.
If you want, you can create the PR using my code/fork. Just credit me for the original implementation, and you can maintain the PR from there.
I won’t open the PR myself since I don’t need this anymore.
