Review m-6. The XML doc said the token is cancelled on timeout only.
ScriptRunGuard links it to the caller's token
(CreateLinkedTokenSource(ct)), so it is also cancelled on shutdown or
when the evaluating actor stops mid-run. The doc now says so.

ScriptContext.CancellationToken is backed by an AsyncLocal that
ScriptEvaluator.RunAsync scopes around the compiled delegate, so it is
exactly the token ScriptRunGuard cancels on timeout. A polling script
can now end its own abandoned run and free the slot. AsyncLocal rather
than a field because the scripted-alarm engine reuses one context per
alarm: an orphan keeps seeing its own cancelled token. The scoping
entry point is internal (IVT to Core.Scripting) so a script cannot
replace its own token.
Editor parity: ScriptAnalysisService dot-completion now walks the
receiver's base chain (instance members only, stopping before
System.Object). Before this, a member declared only on ScriptContext
compiled and published but never completed. DiagnoseTests pins the
member as allow-listed; CompletionTests pins the completion.

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.
First review at 7286d320. Five Low doc fixes (BadNodeIdUnknown comment parity, three stale
Phase7 labels -> design-doc cites, {{equip}} token doc on GetTag/SetVirtualTag). Deadband
NaN/negative-tolerance (004) + a stale docs path (007) left Open.
