fix: collect diagnostics for sub-skills invoked during setup

Previously, sub-skills (e.g. /add-telegram) skipped diagnostics when
called from a parent skill like /setup. This lost channel-level events.
Now all events are collected and shown to the user in a single prompt.

+Every skill sends its own diagnostics event — even when invoked from a parent skill. A `/setup` that invokes `/add-telegram` produces **two** events: `skill_applied` (for add-telegram) and `setup_complete` (for setup). A `/setup` with no channels produces just `setup_complete`.
