Hook handlers run sequentially in descending `priority`. Same-priority hooks

keep registration order.

`api.on(name, handler, opts?)` accepts:

- `priority` — handler ordering (higher runs first).

- `timeoutMs` — optional per-hook budget. When set, the hook runner aborts that

handler after the budget elapses and continues with the next one, instead of

letting slow setup or recall work consume the caller's configured model

timeout. Omit it to use the default observation/decision timeout that the

hook runner applies generically.

Each hook receives `event.context.pluginConfig`, the resolved config for the

plugin that registered that handler. Use it for hook decisions that need

current plugin options; OpenClaw injects it per handler without mutating the
