feat: enforce hard test-tier requirement across all DevPlace workflow agents and feature-builder docs

Update the feature-builder agent prompt, test-maintainer agent, and all four workflow JS files (devii-tool, endpoint, feature, job-service) to codify the DevPlace test standard as a non-optional project requirement: one test file per endpoint, directory tree mirroring the URL/source path, split into three tiers (unit, api, e2e). Add explicit Test phases to devii-tool, endpoint, feature, and job-service workflows, and embed tier-specific test instructions (path mapping, fixture choice, coverage scope) directly in each workflow's meta description and TESTS constant.
