The architect API returned "failed to start conversation" because
projectRepo.Get() failed — the in-memory K8s repo watches the rdev
namespace but projects deploy to the projects namespace. Made project
lookup non-fatal with fallback to default pod. Added error logging to
all architect handler methods (were silently swallowing errors).
Also adds setup-hooks, commit-after-qa, and pre-merge-validate steps
to the foundary cookbook tree for git hooks and code quality gates.
