Root cause: PendingMenuItem::Login carried only a label, so every provider
row collapsed to the id-less Action::Login, and dispatch_login resolved
the FIRST advertised interactive method — the Kimi device flow. Selecting
Grok/Claude/Copilot/Codex all opened kimi.com. (The shell side was already
correct: authenticate() dispatches each method id to its own OAuth flow.)
- PendingMenuItem::Login now carries the advertised method id (None only
on the no-interactive-method fallback row).
- New Action::LoginWith(AuthMethodId); the picker dispatches it with the
row's own id. Action::Login keeps its meaning (resolved/default method)
for /login, auto-login, and re-auth.
- dispatch_login_with resolves the id against the advertised methods and
FAILS CLOSED on an unknown id — no silent first-method fallback — then
adopts the method's label and start mode.
Tests: picker rows pinned to their method ids; LoginWith(claude-pro-max)
must authenticate with claude-pro-max even when kimi-code was previously
resolved; unknown ids surface an error and start nothing.
Verified: kigi-tui 6867 tests green, clippy clean.
