Team owner reset account, now can't admin team

I created a keybase team and added a bunch of people to it. Everything was working great until I lost my Yubikey, and reset my Keybase account to protect myself. Now some commands report I'm not a member of the team, and other commands say I'm still the owner:

```
bash-3.2$ keybase team list-members chadikins
▶ ERROR You are not a member of this team (code 2623)
bash-3.2$ keybase team add-member chadikins --user=tradel --role=owner
▶ ERROR You are not a member of this team (code 2623)
```

So I try to add myself back into the team:

```
$ keybase team request-access chadikins
▶ ERROR You are an implicit admin - no reason to request access. (code 2734)
```

Is there anything I can do besides deleting the team and creating a new one?
Thanks!

Start with the listed `keybase team list-members`, `add-member`, and `request-access` commands using an account that has been reset after losing its Yubikey. Trace how team membership and implicit-admin status are determined. Done means the commands consistently reflect the account's status and provide a clear recovery path or error.
