_updateConnectionIndicator() ran on every keystroke (_reliableSend) and
every ACK (_ackDelivery), unconditionally writing display/className/
textContent/title. During fast typing the rendered output is usually
identical between calls, so those were wasted main-thread DOM writes.
Extracted the branch logic into a pure DOM-free _computeConnectionDescriptor()
returning { display, dotClass, text, title } (every branch/string preserved
verbatim; hidden state normalizes the three non-display fields to '' so the
compare is well-defined). _updateConnectionIndicator() now computes the
descriptor, compares all four fields against a cached _lastIndicatorDescriptor,
and early-returns when unchanged — otherwise caches and writes the DOM exactly
as before (display always; dotClass/text/title only when shown). First call
renders (cache starts null). Perf only, no behavior change.
Tests: test/connection-indicator.test.ts — 9 descriptor cases pinning the
exact strings per state + 4 skip cases (first call writes; two identical calls
write DOM once via counting setters; state change and hidden->shown re-render).
31/31 with input-send-order regression; build, frontend-syntax, prettier clean.
