d fei c7cc8e28d5 fix(sse): stop reloading the whole terminal when a reconnect lands on the same session
handleInit() did not distinguish a first load from an SSE reconnect: it always
cleared the terminal caches in _resetAllAppState() and re-ran selectSession() for
the session that was already on screen. Every reconnect therefore refetched up to
1 MiB of buffer and reset+rewrote xterm. On a link that drops a connection about
once a minute (measured at ~57s intervals against a healthy server) that reads as
the page refreshing itself and throwing away your reading position.

A reconnect that lands back on the still-open session now keeps the terminal
caches and activeSessionId and resyncs through _onSessionNeedsRefresh(). That
path still reloads the buffer, so output produced during the outage is not lost,
but it preserves distance-from-bottom — the same rule #259 established for a
refresh the server triggered rather than the user. The WS is reconnected
explicitly when it is not already on that session, since skipping selectSession()
skips its _connectWs() call.

First load (gen === 1) takes exactly the path it took before.
