Release 1.1.2 — the default path works end to end

Fix release for 1.1.1: the minimal path end to end, engine commands that
run on Godot, Unity and Unreal, hook warnings you can see, and verdicts
that say when they could not check. Details in CHANGELOG.md; upgrade
steps in UPGRADING.md (v1.1.1 → v1.1.2).

Fixes #67
Fixes #131

+## Command Line — Build and Automation Tests (per platform)
+
+Build the project's own editor target before running tests (a fresh checkout has
+no compiled game module), then run the automation tests with the editor. Epic
+recommends building `<Project>Editor` rather than `UnrealEditor`, so the modules
+the `.uproject` disables stay disabled. Give the project as an absolute path.
+
+| Step | Windows | Linux | macOS |
+|------|---------|-------|-------|
+| Build the editor target | `Engine/Binaries/DotNET/UnrealBuildTool/UnrealBuildTool.exe <Project>Editor Win64 Development -Project="<abs>/<Project>.uproject"` | `Engine/Build/BatchFiles/Linux/Build.sh <Project>Editor Linux Development -Project="<abs>/<Project>.uproject"` | `Engine/Build/BatchFiles/Mac/Build.sh <Project>Editor Mac Development -Project="<abs>/<Project>.uproject"` |
+| Editor executable for a command-line run | `Engine/Binaries/Win64/UnrealEditor-Cmd.exe` | `Engine/Binaries/Linux/UnrealEditor` | **NOT SOURCEABLE** — Epic documents only the `Engine/Binaries/Mac/UnrealEditor.app` bundle, not a command-line editor inside it |
+| Packaged build | `Engine/Binaries/DotNET/AutomationTool/AutomationTool.exe BuildCookRun … -platform=Win64` | `Engine/Build/BatchFiles/RunUAT.sh BuildCookRun … -platform=Linux` | `Engine/Build/BatchFiles/RunUAT.sh BuildCookRun … -platform=Mac` |
+
+The automation arguments are the same on every platform:
+`"<abs>/<Project>.uproject" -ExecCmds="Automation RunTests <Project>.; Quit" -unattended -nullrhi -stdout -FullStdOutLogOutput`.
+`RunTests` is a partial (substring) match. Each test prints
+`Test Completed. Result={<status>}`, and the run ends with
+`**** TEST COMPLETE. EXIT CODE: <n> ****` — exit code 0 means no test failed.
+Only one `Automation` run request is allowed per `-ExecCmds`, and `-testexit=` is
+legacy.
+
+The Windows column was run on UE 5.7. The Linux and macOS columns come from
+Epic's documentation and forum answers by Epic staff (sources below); Epic never
+prints the full Linux test line, so it is assembled from the executable and the
+platform-neutral arguments.

+### Clamping Attributes
+
+Attribute Sets have no built-in clamping: the Data Table `Min Value` and
+`Max Value` columns have no effect. Clamp in the Attribute Set:
+- `PreAttributeChange()` is called just before any modification to an
+  attribute, and is the hook for rules like
+  `Health = Clamp(Health, 0, MaxHealth)` — its `NewValue` is mutable.
+- `PreAttributeBaseChange()` is called just before a change to an attribute's
+  **base** value when an aggregator exists, and `PostGameplayEffectExecute()`
+  just after a Gameplay Effect is executed to modify the base value — clamp
+  base-value changes from instant effects there.
+
+Stacking rules govern re-applications of the same Gameplay Effect; they do not
+bound one attribute pushed by different effects.
