Project UAI Bridge 3.6.2 — OpenCode execution permission gate

Fixes the remaining OpenCode tunnel failure after 3.6.1:
OpenCode could not verify that a desktop tool was blocked.

The bridge installs a private execution permission gate in its isolated OpenCode
server, preserving the native tool schemas required by free models. It waits for
the selected tool's matching pending permission and confirmed interruption before
returning blocked-action feedback. Exact UAI calls on the private remote MCP
server retain the normal Roblox tool handoff.

Existing desktop 3.6.0 installs download this verified bridge update automatically
and activate it when work and retained receipts are idle. Client remains 3.6.1;
desktop and Android downloads remain 3.6.0. This release contains only the bridge
manifest and package. No new desktop executable is needed.

Verification results and their limits are recorded in
