v2-ci / unit-tests (push) Has been cancelled
feat(cli): historyread --events reads event history over the wire (lmxopcua#776)
Item 1 of #776 (the B2 over-the-wire ask): Client.CLI had no way to issue a
HistoryReadEvents. `historyread --events` now sends ReadEventDetails to an
event notifier and prints one line per event in select-clause order.
--fields picks the select clauses (default EventId, EventType, Time,
SourceName, Severity, Message, ConditionName (on ConditionType), SourceNode);
--of-type adds an OfType where-clause. --events is exclusive with --modified /
--aggregate, and --fields / --of-type require it.

Client.Shared gains IOpcUaClientService/ISessionAdapter.HistoryReadEventsAsync
(default-implemented as NotSupported for other implementations) backed by the
real session adapter through HistoryReadPaging, so continuation points are
followed up to --max and a Bad node status is surfaced, not printed as empty.

Tests: CLI tests over the fake service (default filter, --fields/--of-type
filter, option conflicts); an over-the-wire test drives the shared client's
event read against the in-process server — the default fields come back
non-null, OfType filters, an invalid where-clause is BadEventFilterInvalid.
The other #776 items are decisions and are left open.
