chore: download latest EQL instead of bundling hardcoded SQL files

Remove hardcoded EQL SQL files from local/ and packages/schema/.
The local Docker setup now downloads the latest EQL release at
build time, and the drizzle migration generator fetches it at
runtime. This matches the pattern already used in stack-forge.
