v0.7.2

0.7.2

• The idle nudge no longer kills the first prompt of an opencode session.
  chat.message pushed its nudge as {type, text, synthetic}, and opencode
  validates every part of the user message in SessionPrompt.createUserMessage
  before the request leaves the client: the missing id, sessionID and
  messageID raised a SchemaError, then
  EventV2.InvalidDurableEvent: Expected string aggregate field sessionID. The
  host rendered that as "unexpected server error" — reproducible on the first
  prompt of a session, the only one the idle clock lets the nudge through, and
  invisible to the gateway, which never saw a request. The part now copies
  sessionID/messageID from the message it rides in and carries its own id.
  tests/test_plugins.py runs the hook under node and asserts the three ids.
• Claude Code, Codex and pi were never affected: they take the nudge as hook
  stdout or as a host message, not as a message part.

No service change; the release is the plugin.
