Step 3 of #8, into the stonecutter integration branch. 1.21.9 now builds from src/ as :1.21.9, and versions/1.21.9/src is gone.

Why no code changes

1.21.9's copy (and its build.gradle) was byte-for-byte identical to the old 1.21.10 copy, so the version comments from step 2 (>=1.21.11 / <1.21.11) already cover it. This PR only:

adds 1.21.9 to stonecutterVersions
removes versions/1.21.9/src, build.gradle and settings.gradle, and the now-unused loom_version
updates VERSION_GUIDE.md and the README (the versions left are 1.21.4–1.21.8)

Like 1.21.10 in step 2, 1.21.9 now renders hats (it had the same empty render-queue override), and gets the display-name null check.

Checks

1.21.9 jar vs the old :mc-1.21.9 jar: same entries, identical fabric.mod.json and mixin configs. Comparing bytecode (ignoring line numbers), only HatFeatureRenderer, ObjModel, ObjRenderer, PlayerEntityRendererMixin and ShaderUtils differ, the same set as 1.21.10 in step 2.
Switching versions: Set active project to 1.21.9 compiles, and Reset active project leaves src/ unchanged.
Builds: a cold buildAll --no-build-cache builds all 8 jars in 82 s, and compileJava passes.
In game: :1.21.9:runClient starts (offline in dev: there's no DevAuth in that run folder).

Needs an in-game check: hats on 1.21.9.

Step 3 of #8. 1.21.9's copy was identical to the old 1.21.10 one, so the
existing version comments already cover it and no code changes: 1.21.9 is
added to stonecutterVersions and versions/1.21.9/src is removed.

Like 1.21.10 in step 2, 1.21.9 now renders hats (1.21.11's render-queue
implementation) and gets the display-name null check. The jar has the same
entries, fabric.mod.json and mixin configs as before; only those classes
and ShaderUtils's entityAlpha helper differ in bytecode.
