refactor(hub): skip capabilities.build:false devframes silently

The skip is the declared behavior, not a condition to report; drop the
DF8007 diagnostic and its docs page.

 Browser-side tools keep working in full: a page script still loads into the host page and talks to its panel over the [in-page channel](/guide/in-page-channel) (the a11y inspector scans a production app exactly as it does in dev). Reads resolve from the baked dump (`static`/`snapshot` RPCs, shared-state snapshots); live writes (messages, command execution) have no server, so the browser clients degrade to local no-ops, and a panel's dock-activation deep links ride a same-origin `BroadcastChannel` instead of the RPC relay.
 
-A devframe whose value is inherently live declares `capabilities.build: false` and stays out of the build entirely - no dock, no SPA copy, no RPCs in the dump (`DF8007` logs each skip). The built-in terminals, code-server, and assets devframes declare it, so a hub mounting every built-in bakes only the tools that mean something statically. See the [buildHub options](/references/hub-api#buildhub-options) reference, and [`examples/a11y-messages-playground`](https://github.com/devframes/devframe/tree/main/examples/a11y-messages-playground) for a Vite host whose `vite build` output ships the hub.
