fix(hooks,tools): replace /plan example with prometheus delegation and rename code-review example to review-work (#2633, #3285, #2873)

- context-info-builder referenced a non-existent /plan command;
  now directs users to the Prometheus agent for planning
- skill tool description example referenced 'code-review' which
  does not exist; changed to 'review-work' (actual built-in skill)
- skill tool execute path now surfaces the missing host permission
  gap so callers understand OpenCode plugin context limits
