feat(telegram,discord): compact permission messages with expandable details (#952)

* feat(telegram,discord): compact permission messages with expandable details

Replace verbose permission request messages with a compact format showing
only the tool name. Adds a "See more" button that expands inline to show
tool_name, description, and pretty-printed input_preview JSON. Yes/No
buttons replace Allow/Deny. Bump plugin versions to 0.0.4.

* revert: restore Allow/Deny button labels
