permission.ask plugin hook is never triggered

packages/plugin/src/index.ts:261 declares a permission.ask hook:

"permission.ask"?: (input: Permission, output: { status: "ask" | "deny" | "allow" }) => Promise<void>

Nothing ever calls it. trigger( appears in six places across the repo —
shell.env (x2), experimental.chat.system.transform,
experimental.chat.messages.transform (x2) and tool.definition — and
permission.ask is not among them.

So a plugin that registers the hook is silently ignored: no warning, no error,
the handler simply never runs.

Reproduce

Plugin:

export default async () => ({
  "permission.ask": async (input, output) => {
    console.log("permission.ask fired", input.permission)
    output.status = "deny"
  },
})

Point opencode.json at it and ask the agent to run any shell command. The
command runs, nothing is logged, and the hook never fires.

Why it matters

There is no other interception point for permission decisions. Denying has to
be done by throwing from tool.execute.before, allowing has to be done by
auto-answering the permission.asked event after the prompt has already
appeared, and permission requests that are not tool calls (external_directory,
sandbox escalation) never reach a plugin at all.

Happy to send a PR — I have one working.
