Deployment view #11

A Deployment view in the Fallout container, showing the continuous-delivery model — channels → environments → targets.

Implemented on feature/views-and-run-config (#2) as a placeholder: DeploymentProvider.getChildren() returns [], and the view shows welcome content explaining why.

The blocker

The framework doesn't emit a deployment graph. Verified against the current build-graph.json, whose top-level keys are version, falloutVersion, targets — nothing about channels or environments. The CD model is ADR-0009 territory; this view lights up once a deployment-graph.json exists.

Decision needed before the release

This currently ships a permanently empty view. Two defensible options:

1. Ship the placeholder — it advertises the roadmap and the welcome text explains the situation. Costs a dead UI element on first impression.
2. Strip it, re-add when the graph lands — cleaner first release. Costs re-doing the registration later, which is small.

Worth deciding deliberately rather than by default, since it's the first thing a new user sees in the container.

Acceptance (if kept)

• View registers and shows welcome content rather than an empty tree
• Welcome text states plainly that the framework doesn't emit the graph yet
• No error or console noise when there's nothing to show

Depends on #9.
