/login previously fired the resolved method's flow immediately — there was
no way to see providers or their status. It now lands on the provider
picker; already-connected providers show a green 'connected' badge in the
key column.
Shell: initialize() probes stored credentials once (primary session flag,
auth.json oauth/<provider> scopes, resolved platform keys env>auth.json>
config) and stamps _meta.connected on each advertised method
(connected_method_ids + stamp_connected_meta, pure and unit-tested).
Display state only — never an authorization input.
TUI:
- PendingMenuItem::connected() reads the badge from method meta; the
picker renders it green (accent_success), replacing the shortcut hint.
- New Action::OpenLoginPicker: /login shows the picker; mid-session it
stashes the view like dispatch_login, and starts no flow by itself.
- Mid-session picker: last row reads 'Cancel' and dispatches CancelLogin
(clicking it must not exit the app); Esc also returns to the session.
- After a successful login, the just-authenticated method is stamped
connected in the TUI's advertised-methods copy (auth_in_flight_method →
AuthComplete), so a later /login shows the badge without re-initialize.
Verified: kigi-shell 5256 + kigi-tui 6870 tests green, clippy clean.
