chore: remove unused homelab/runner directory

We use homelab/docker-compose.yml (full stack) for the homelab deployment,
not homelab/runner/docker-compose.yml (runner-only subset). Removing the
unused directory to prevent confusion.

homelab/runner/docker-compose.yml

-# LibNovel homelab runner
-#
-# Connects to production PocketBase and MinIO via public subdomains.
-# All secrets come from Doppler (project=libnovel, config=prd_homelab).
-# Run with: doppler run -- docker compose up -d
-#
-# Differs from prod runner:
-#   - RUNNER_WORKER_ID=homelab-runner-1  (unique, avoids task claiming conflicts)
-#   - MINIO_ENDPOINT/USE_SSL → storage.libnovel.cc over HTTPS
-#   - POCKETBASE_URL          → https://pb.libnovel.cc
-#   - MEILI_URL               → https://search.libnovel.cc (Caddy-proxied)
-#   - VALKEY_ADDR             → unset (not exposed publicly)
-#   - RUNNER_SKIP_INITIAL_CATALOGUE_REFRESH=true
-#   - REDIS_ADDR              → rediss://redis.libnovel.cc:6380 (prod Redis via Caddy TLS proxy)
-#   - LibreTranslate service for machine translation (internal network only)
-#
-# extra_hosts pins storage.libnovel.cc and pb.libnovel.cc to the prod server IP
-# (165.22.70.138) so that large PutObject uploads and PocketBase writes bypass
-# Cloudflare's 100-second proxy timeout entirely. TLS still terminates at Caddy
-# on prod; the TLS certificate is valid for the domain names so SNI works fine.
