Import 13 skills from the old opencode setup into turnstone

skills/ carries the SKILL.md files; scripts/import_skills.py runs
inside the VM via turnstone's own storage layer (SKILL.md parser +
risk scanner) so rows match what the console admin API would write.
Server must be restarted after import (stale WAL snapshot).

+### Skills
+
+The 13 skills from the old opencode setup (`~/marvin/configs/opencode/skills`,
+copied into this repo under `skills/`) are imported into turnstone's
+DB-backed catalog via `scripts/import_skills.py`. The script runs
+INSIDE the VM (uses turnstone's storage layer + SKILL.md parser +
+risk scanner):
+
+```sh
+scp -O -i configs/ssh/id_ed25519 -P 2222 -r skills scripts/import_skills.py \
+    marvin@localhost:/tmp/
+ssh -i configs/ssh/id_ed25519 -p 2222 marvin@localhost \
+    /opt/turnstone/bin/python /tmp/import_skills.py --dir /tmp/skills
+```
+
+Idempotent (`--update` re-imports + appends version rows). **Reboot the
+VM after importing** — the running server holds a stale WAL snapshot
+and won't see new rows until restart.

 ## Notes / trade-offs
 
 - boco boots with `-snapshot`: **only the virtiofs shares persist.**
