Roost v0.9.1 — Slim tiles read right

A small polish patch on top of v0.9.0.

🔧 Fixes

• Slim tiles read right. In Slim density, launch tiles (apps, web apps, shortcuts) now show their action verb — "tap to open" / "tap to run" — instead of "ready", which was fire-state wording that never applied to a tile that just opens something. Fire tiles (HTTP actions, Home Assistant scenes) still show ready / firing… / the status code. Regular and Rich were already correct and are unchanged.

📚 Docs

• Refreshed the density screenshots (they still showed the pre-unification app-grid + ACTIONS split) and aligned the http-actions §Density prose; marked ADR-0007 accepted.
