* fix(sessions): fork icon + depth number, no indentation
Multiply-nested forked sessions rendered with deep indentation that crushed
the card off-screen and made titles unreadable, and the per-sibling order
number was uninformative (mostly "1").
- SessionTreeItem: replace forkIndex (sibling order) with forkDepth (nesting
level: 1 = child of a root, 2 = fork of a fork, ...); flattenSessionTree
populates it.
- SessionCard: render CallSplit fork icon + the depth number (primary tint).
Removed the depth-based start padding so names stay full-width readable —
the icon+number now carries the structure instead of indentation.
- strings: sessions_fork_indicator (en/zh/ko).
- SessionTreeTest: assert isFork/forkDepth across nested fixtures.
No backend change — backend already returns parent_session_id per SessionInfo.
* test(ws): make testAutoReconnect tolerate transient RECONNECTING state
The test gated on connectionStatus.first { it == RECONNECTING } with a
15s timeout. With the test backoff forced to 0ms the RECONNECTING state is
emitted + consumed before the collector attaches, so the wait missed it and
timed out (kotlinx.coroutines.TimeoutCancellationException) — the flake CI
saw under parallel load.
- Replace the brittle RECONNECTING .first{} wait with a tolerant check that
accepts RECONNECTING-or-later (the reconnect clearly fired).
- Keep connect2Latch (second socket opening) as the definitive proof + add a
final CONNECTED assertion.
- Reset the test backoff in a finally so later tests never inherit 0ms.
