H1K0 16e68236a0 build(project): ship the dedup CLI in the runtime image
The backend build stage compiled only ./cmd/server, so the dedup maintenance
tool was never available on deploy. Build it alongside the server and copy
/out/dedup to /app/dedup in the runtime image (which already has ffmpeg/ffprobe
for video frames and the /data volume). Run it with `docker exec`.

# =============================================================================
# Tanabata File Manager — single-image build
#
# Produces one container that serves the SvelteKit SPA (built to static files)
# and the Go API on the same port. There is no Node runtime in the final image:
# the frontend uses adapter-static, so stage 1 emits plain HTML/CSS/JS that the
# Go binary serves directly (see STATIC_DIR).
