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

+## Version Awareness
+
+**CRITICAL**: Your training data has a knowledge cutoff. Before suggesting engine
+API code, you MUST:
+
+1. Read `docs/engine-reference/unity/VERSION.md` to confirm the engine version. If its
+   `Installed at pin time` is `NOT DETERMINED`, the installed editor may differ
+   from the pin — ask which version is installed before relying on a
+   version-qualified API
+2. Check `docs/engine-reference/unity/deprecated-apis.md` for any APIs you plan to use
+3. Check `docs/engine-reference/unity/breaking-changes.md` for relevant version transitions
+4. Read `docs/engine-reference/unity/current-best-practices.md` and `plugins/dots-entities.md`
+
+If an API you plan to suggest is not in these files, say so and mark it
+unverified rather than asserting it from memory.
+
+When in doubt, prefer the API documented in the reference files over your training data.
