Subject: [PATCH 2/3] docs: clarify ai.* are repo-local Maven build properties,
 not mojo @Parameters

Prevents future audits from mistaking the -Dai.* flags (ai.model, ai.gpuLayers,
ai.mainGpu, ai.devices, ai.index.output.directory) for stale/invalid properties.
They ARE valid: repo-local Maven <properties> in srcmorph-maven-plugin/pom.xml,
wired into this module's own gpt-oss self-test/benchmark executions and
overridable with -Dai.*. Downstream consumers of the published plugin set the
same knobs as <configuration>/model-definition elements; the published mojo
parameters are the separate srcmorph.* set.

- pom.xml: header comment above the ai.* property block.
- README.md: note before the -Dai.* usage in "Recommended Models".
- CLAUDE.md: bullet documenting the two property namespaces.

Comment/doc-only; no build behavior or parameters changed.

Subject: [PATCH 3/3] docs: make the downstream GPU section use <aiDefinition>
 config elements
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The "GPU acceleration (opt-in)" section targets downstream users of the
published plugin, but its tuning bullets described the knobs via -Dai.gpuLayers
/-Dai.mainGpu/-Dai.devices — which are this repo's own Maven build properties
and do NOT exist in a downstream build. Reframed the two bullets to set
<gpuLayers>/<mainGpu>/<devices> inside the user's <aiDefinition> (the real,
documented config elements, cross-referenced to "Per-model <aiDefinition>
parameters"), and kept -Dai.* only as an explicit "this repo's own presets"
parenthetical. Consistent with the ai.* clarification note added earlier.

Doc-only.
