Danijel Martinek f77e6ea881 chore(template): clean-slate template snapshot from bb4a0c7
Curated, product-agnostic snapshot of the post-story-04 tree: demo
content deleted, auth-only reference feature, web-next shell, all gates
green. Product-specific docs, ADRs 027-029, PRDs/epics/archive, editor
library traces, and product naming are curated out; generic template
repairs (coverage provider devDeps, root test:coverage script, live
lint fixes, root-only release-please) are kept. See TEMPLATE.md for
provenance, curation list, and usage.

# Sandcastle sandbox image — runs the implementer + reviewer + decomposer
# agents. Shape required by @ai-hero/sandcastle: a non-root `agent` user
# (UID/GID aligned with the host so bind-mounted files share owner), Claude
# Code CLI on PATH, and a long-running ENTRYPOINT so the container survives
# the gap between sandcastle creating it and exec'ing into it.
#
# Authenticates via the host's mounted ~/.claude/ session (subscription
# mode — sandcastle issue #191 workaround, our primary flow). Falls back
# to ANTHROPIC_API_KEY when no host credentials are present.
