Fail build and copy generators with ETIMEDOUT after 600000ms and terminate the complete managed process tree. Keep the timeout policy in the bundled-assets caller while preserving the shared helper for distinct callers such as #111349.

Adds a Discord Activities integration so an agent can show a self-contained
HTML widget to Discord users, opened as a sandboxed Activity inside the client.
Off by default: routes, the discord_widget tool, and the launch handler register
only when channels.discord.activities is configured. OAuth identifies the user
and gates on the account allowlist; widget lookup is capability- or
instance-validated; token exchange is rate-limited; widget HTML runs in a
no-network sandboxed iframe.
