v0.3.0

Minor Changes

• e98bf43: v0.3 — CI story: attunement CLI. check --schema <module> <files...> validates config files against the app schema (same did-you-mean errors as runtime), --diff fails on top-level key drift between environments, secret hygiene warnings (credential-like names, high-entropy values), docs renders a markdown table of keys/types/defaults from a zod schema. New attunement/cli entry + attunement bin.
