Session close
This is the clearer public alias for session-summary. Existing names remain supported.
Resolve this skill directory as SKILL_DIR. Read CLIENT.md beside this file, then read and follow ../session-summary/SKILL.md completely as the canonical close-out procedure. Use this alias's scripts/session_save.py launcher when that procedure refers to the kernel.
Do not use this for an in-progress checkpoint or change the canonical close-out contract.
