Subject: [PATCH] feat: add AI_EMBEDDING_SUPPORTS_MRL env var to decouple
 pgvector dimensions from model API

Some embedding models don't accept a `dimensions` parameter. This adds
an optional env var that controls whether the dimension is sent to the
model API, while always using it for pgvector indexing. Preset models
have this handled automatically; the env var allows explicit override
for custom models.
