Subject: [PATCH] fix(tui): stop blocking first render on the full provider
 catalog

The blocking bootstrap waited for GET /provider, which returns every
models.dev provider and model: 6.6 MB, 226 providers and 8,405 models
for an install with one provider connected. Building and encoding it
costs the server worker 1.2 s warm (4.1 s on first call) on a loaded
host, and the TUI parses all of it before the prompt can appear.

Only the connect dialog reads provider_next, and the store already
starts with an empty value, so the request moves to the non-blocking
group that runs after the prompt is shown.

Launch to a typable prompt, compiled binary, macOS M2 Pro, median
(min-max) of 10 relaunches in ABBA order:

  home screen           2235 (2183-2277) ms -> 1976 (1928-2048) ms
  3,906-message session 2575 (2523-2625) ms -> 2331 (2295-2421) ms
