A client's first screen lists their apps in plain sentences, each saying whether its agents work or wait #1812

Replaces #1607, red twice on the spawned-child suites. Done looks like:

• [ ] Signed in through a child forge's claim link, a person first sees their apps, each with one plain-words line and its agents working or waiting; no map, board or settings until asked.
• [ ] A test asserts none of "pull", "branch", "commit", "merge", "CI", "repository" appears.
• [ ] The existing child-forge tests (no model key note, <name>--<parent host> address on the home) stay green: run them before pushing.

Start from today's main. Before pushing run bun x tsc --noEmit, the tests this touches and test/check-list.test.ts; name every new test file in GATE in scripts/gate.ts in the same commit. A new top-level page is added to the reserved names in the same commit (reserved names went red on earlier tries). A test that goes red in this pull is fixed in this pull.
