Jean-Gabriel Gill-Couture eea006535b refactor: drop harmony_app landfill

Scores own deploy. harmony_app is identity, images, context, and
HarmonyApp→Scores. Authoring DX lives in dx. Compose/chart/Application
model and the Helm render test are gone.

Getting started: one file per component

Junior-shaped ship inventory (ADR-029). Opening frontend.rs is the frontend. There is no FrontendCommand type.

cargo check -p example-dx-guide-ship

Copy this layout

File	What it is
`src/main.rs`	Inventory: `.component::<Frontend>()` + contexts
`src/frontend.rs`	`impl Command` (`npm run dev`) and `impl Container`
`src/backend.rs`	Same, plus `env()` wiring via `Ref<Postgres>` etc.
`src/postgres.rs`	Container (or Remote in production). `PostgresScore`
`src/zitadel.rs`	`ZitadelScore` — do not invent `AppScore`
`src/bucket.rs`	`BucketScore`
`src/localdev.rs`	`Context::new("localdev").bind::<Frontend>(Runtime::Command)`
`src/production.rs`	Frontend/Backend as Container; managed bits as Remote
`src/harmony.rs`	Stub framework types. Not `harmony_app`.

Runtime is an enum

Context::new("localdev").bind::<Frontend>(Runtime::Command)

Runtime is Command | Container | Remote. Binding Runtime::Command on Postgres compiles. The type system does not know Postgres has no impl Command. That is the tradeoff: obvious API, few traits, illegal binds are not a type error. (The other DX crates make that a type error.)

Cycles

Frontend::env takes Ref<Backend> and Backend::env takes Ref<Frontend>. Those URLs are allocated before either side starts. A Ref is desired state, not a live connection.
