Documents `_meta["ai.nimblebrain/http-proxy"]` for bundle authors: manifest declaration (target/mount/websocket), the route shape (`/v1/ws/<wsId>/apps/<bundle>/<mount>/*`), the three injected env vars (NB_WORKSPACE_ID, NB_PROXY_PREFIX, NB_PUBLIC_ORIGIN), and the CSP declaration required on `ui://` resources to frame the proxied URL. Trust model spelled out plainly: same-origin code in the user's session, treat http-proxy bundles like browser extensions, the operator vouches for the code. Lists what the platform DOES enforce (loopback target, header strip, response strip, membership check, per-workspace kill switch) and what it does NOT (no per-bundle origin isolation, no WS upgrade yet). Cross-links to `synapse-astro-editor` as the reference implementation. Added to the Building Apps sidebar between UI Resources and Theming.

Summary
New page documenting the http-proxy primitive added in nimblebrain#128.
Bundle authors need to know:
The page also lists platform-enforced defenses (loopback target, header strip, membership check, kill switch) and known gaps (no per-bundle origin isolation, WS not yet wired).
Cross-links `synapse-astro-editor` as the reference implementation.
Added to the Building Apps sidebar between UI Resources and Theming.
