refactor: collapse packages/atproto and packages/clickhouse into apps/web/app/lib/
Move the two workspace packages into the Adonis monolith under app/lib/.
Adds #lib/* subpath import alias in apps/web/package.json. Rewrites all
25 import sites from @skystar/atproto / @skystar/clickhouse to #lib/atproto/index
and #lib/clickhouse/index. Removes tsconfig references/paths, removes the
workspace entries from root package.json, removes Dockerfile package build
steps, and updates the spec doc to reflect the single-app layout.
169 tests still pass. Build, lint, and docker compose build all exit 0.
