Adds <summary>/<param>/<returns>/<inheritdoc> where missing and removes
project bookkeeping IDs (task/tracking refs) from shipped code comments,
so the docs read cleanly and CommentChecker is quiet except for known
false positives (PLC/protocol terms, event/IEqualityComparer inheritdoc).
Doc/comment-only; no logic changed; solution builds clean.
Addresses Task 1 code-review: document that ReadEventsAsync.maxEvents is enforced
client-side (no server cap in the wire contract); add Platforms=AnyCPU;x64 to match
sibling drivers; use ValueTask.CompletedTask in FakeHistorianGatewayClient.
