Include shared/, docker/, and tasks/ in the built wheel

[wiggzz]

Why

ade_bench/handlers/trial_handler.py resolves shared/ as Path(files("ade_bench")) / "../shared" — i.e. a sibling of the installed ade_bench package. This works for editable installs (hatchling puts the source root on sys.path, so the source-tree shared/ is reachable) but breaks for any non-editable install — git, wheel, PyPI — because hatchling's auto-discovery only ships the ade_bench package, not the sibling data directories.

Symptom from a non-editable install:

open .../site-packages/shared/defaults/docker-compose-duckdb-dbt.yaml: no such file or directory

Same root cause affects docker/ (referenced by compose build contexts) and tasks/ (consumed by ai-codegen-api's evaluate.py to enumerate task definitions — currently forces a full ade-bench checkout alongside any consumer). Bundling these makes pip install ade-bench self-sufficient — no sibling checkout required.

What

Force-include shared/, docker/, and tasks/ in the wheel alongside ade_bench/. Built wheel size is ~13 MB.

Verified by building the wheel and confirming shared/defaults/docker-compose-duckdb-dbt.yaml, docker/base/*, and tasks/airbnb001/task.yaml are present.
