parseLiteralProxyJump: handle bracketed IPv6 + reject invalid ports.
The literal parser used LastIndex(":") to split host from port, which
for [2001:db8::1]:22 left host as "[2001:db8::1]" and produced an
invalid double-bracket address through net.JoinHostPort. Recognise
the bracketed form explicitly via a parseBracketedHostPort helper
and strip the brackets. Validate port is in [1, 65535] instead of
accepting any integer (Atoi happily parses negative or out-of-range
values). Split the host/port branch into its own function so the
nesting stays under the golangci nestif limit.
ssh-create-page: dedupe on append.
setExecutors([...current, next]) would double-list the same executor
if a WS event (or another refresh) inserted it while createExecutor
was in flight. Skip the append when current already has the id.
ssh-image fixture: time-bound docker probe + build.
hasSSHContainerSupport ran `docker info` with no timeout — an
unreachable / hung daemon would stall the Playwright worker
indefinitely. Cap at 10s for the probe. buildE2ESSHImage runs
`docker build` with no timeout; cap at 15 min so a stuck registry
pull or BuildKit hang fails fast.
