feat: Hot reload responses now report time outside the phases, name sibling rows in the Skipped count, and note added test methods - #3188

Reading where a slow run spent its time meant subtracting the three phases from TotalMs by hand, and on large assemblies that remainder (file resolution, planning, the unchanged-method checks) is the longest part of the run. - HotReloadTimingBreakdown now computes OtherMs and refuses a total shorter than its phases, since the phases are spans inside the total. - The response copies OtherMs next to the phases. - The group processor test helper passed a total of 0 after phases the stubs really waited for; it now times the call it makes, as the production run does.
An Applied run could end its message with "Skipped: 1." when the only Skipped row belonged to a sibling file the run re-applied on its own. Outcome leaves those rows out, so the bare count read as if one of the requested edits had been skipped. - When some Skipped rows are sibling rows, the clause now reads "Skipped: n (m in sibling files the run re-applied on its own; Outcome does not count those)."; otherwise it is unchanged. - The clause is built once and used by both the ordinary applied message and the type-only message, which reported the same count. - SkippedTotal and Outcome keep their rules.
… yet A run that adds a [Test] method reports Outcome=Applied, and the fact that the Unity Test Runner will not discover the method until a compile was only in Warnings. Its Added row in Methods had an empty LifecycleNote, so a reader of the row alone missed it. - The worker now gives the entry of an added method with a test attribute a LifecycleNote saying so, under the same condition as the existing warning (added method and a test attribute). - The one-shot lifecycle note still wins, so the rows that carry it keep it unchanged. Edited existing test methods get no note.
The hot reload output reference now describes the three response changes: Timing.OtherMs replaces the sentence that TotalMs exceeds the sum of the phases, Message names how many Skipped rows came from re-applied siblings, and an added test method's row carries a LifecycleNote. The generated skill copies are regenerated from it.
- Both lifecycle note field comments said the note is null unless the method is a one-shot lifecycle method, which no longer holds now that the worker also notes added test methods. - The comment above the Skipped clause in the applied message said the count was taken there; it is now built once and only appended. Comments only.

Append the skipped suffix to the body-edited type message.
If a retained introduced type has a patched body and a re-applied sibling has a Skipped row, TryBuildBodyEditedMessage returns at Line 88. The new append at Line 101 never runs. The response then reports patched bodies without identifying the sibling skipped rows. Append skippedCountSuffix to that successful branch too.

Summary
Timingnow reportsOtherMs: the part ofTotalMsoutside the three phases (file resolution, planning, the checks that find unchanged methods). On large assemblies this is the longest part of a run, and it no longer has to be computed by hand.Skippedrows belong to sibling files the run re-applied on its own,Messagesays how many:Skipped: 3 (2 in sibling files the run re-applied on its own; Outcome does not count those).Addedrow of a method with a test attribute now carries aLifecycleNotesaying the Unity Test Runner will not discover it untiluloop compile.User Impact
Each of these values was already correct, but easy to misread when looking at one place in the response:
[Test]method answeredOutcome=Applied, and the fact that the Test Runner cannot see the method yet was only inWarnings. ItsAddedrow had an emptyReasonandLifecycleNote.Outcome=Appliedrun could end its message withSkipped: 1.when the only Skipped row was a sibling's.Outcomeonly judges the requested files, but nothing in the message said that row was not one of them.TotalMs - AnalysisMs - ShimCompileMs - PatchMsto find.The totals (
SkippedTotaland the others) and theOutcomerules are unchanged, and so is the existing warning text.Before / after (placeholders)
Timing:Message, Skipped clause of an applied run:... Skipped: <n>.<m>of<n>in sibling files... Skipped: <n>.... Skipped: <n> (<m> in sibling files the run re-applied on its own; Outcome does not count those).The type-only message (
Hot reload introduced <k> type(s); no method body needed patching.) ends with the same clause.Addedrow of a new test method:Changes
HotReloadTimingBreakdowncomputesOtherMsand refuses a total shorter than its phases withArgumentOutOfRangeException, since the phases are spans inside the run. The response copies it. The Go CLI passesTimingthrough as a map, so it is unchanged.HotReloadRequestedFileOutcomeSummary.CountSkippedSiblingOutcomescounts the Skipped rows of re-applied siblings, using the same sibling set thatOutcomeleaves out.HotReloadApplyResponseBuilderbuilds the clause once and hands it to both the ordinary applied message and the type-only message.HotReloadIntroducedTypeResponseSection.TryBuildMessagenow takes the clause instead of a count. The other message branches are untouched.LifecycleNoteto the new note under the same condition as the existing warning: an added method with a test attribute. A one-shot lifecycle note still takes precedence.Addedrows that are not Unity messages, so the Editor side is unchanged.LifecycleNoteare not affected. One counts patched rows only; the other matches the forwarded Unity message notes exactly.references/output.mddescribes all three changes, and the generated skill copies are regenerated.lifecycleNotefield comments said the note is null unless the method is a one-shot lifecycle method.Existing tests changed

Its only Skipped row is a sibling's.HotReloadToolTests.BuildApplyResponse_SiblingRowsAllSkipped_AddsNoReappliedCount: adds one assert forSkipped: 1 (1 in sibling files.HotReloadToolTests.BuildApplyResponse_WithTiming_CopiesEveryPhase: adds an assert forOtherMs.HotReloadGroupProcessorTests.RunGroupWithPhaseStubsAsync(test helper): it completed the timing with a total of0after phases the stubs really waited for, and the new invariant rejects that. It now times itsProcessGroupAsynccall with aStopwatchand passes that total, as the production run does. The three tests that use it pass unchanged.The other tests that expect
