cliffhall 219298b24d feat(web): add Console (stderr) tab; show it on stdio connect failure (#1621)
A failed stdio launch had no useful diagnostic surface: the message log
(History) is cleared on the error transition and there are no HTTP
requests (Network), so the auto-opened monitoring column was empty. The
process's stderr — which explains the failure (e.g. "No module named
mcp_server_time") — was captured in StderrLogState but never displayed.

- New ConsoleScreen renders the captured stderr stream (search / sort /
  clear / export; embeddable in the monitoring column), wired through App
  via the existing useStderrLog hook + StderrLogState.
- Console is a pinnable monitor tab like Logs/History/Network, gated to
  stdio servers (HTTP has no child process). It lives in the header menu
  when the column isn't pinned, and moves into the column when it is.
- The failure column now picks its tabs by which diagnostic actually
  captured content (stderr → Console, fetch requests → Network), not by
  the active server's transport: a connect failure fires the client
  `disconnect` event, which clears `activeServer`, so transport can't be
  read back there. The memo re-runs as stderr/fetch entries stream in, so
  the diagnostic tab appears as soon as the failing process prints.

Verified live against a failing `python -m mcp_server_time` stdio server:
the column auto-opens to Console showing the real ModuleNotFoundError.
