"""Persist ``skill`` on a2a_messages.
Directed A2A ``send()`` accepts a ``skill=`` (the capability the sender is
exercising/requests of the receiver, e.g. ``code_review``) and the gateway
callers (qa / doc / pr_gate) pass it expecting the receiver to learn which
capability the message is about. Until now ``send_chat_message`` never read it
from options, so it was silently dropped — the receiver's inbox showed a bare
message with no skill context. This adds a nullable ``skill`` column so the
capability rides on the row and surfaces in the inbox model.
