fix: move session-complete from Stop to SessionEnd hook (#1330)

The `session-complete` command in the Stop hook runs every turn,
killing the SDK agent via SIGTERM. This causes the next summarize
call to receive an empty response because the agent needs to restart.

By moving `session-complete` to SessionEnd (which only fires on
actual session termination), the SDK agent stays alive between turns
and summarize works reliably.

Fixes #1314
