mise: drop packages:build from dev and test tasks
Adonis uses tsx under the hood for node ace serve --hmr and node ace
test. tsx reads the tsconfig paths alias and resolves @skystar/atproto
directly to packages/atproto/src/index.ts at runtime — no dist files
needed. The packages:build step is only required for the production
build path (node ace build, the Dockerfile), which remains unchanged.
