fix(drill): lay the harness's kit down before boot instead of reloading Kits (#22)

Run 48 deleted Kits' file for a fresh start, and the harness's
rnhrevolver kit, added after boot with `oxide.reload Kits` through the
panel's command endpoint, never reached Kits: no reload or compile job
followed, and every test profile was refused for want of the kit.

The drill now replaces kits_data.json with one holding only that kit.
Kits reads it at boot; RunicNPC's first load adds its example kits
beside it (it skips kits already there) and settles its own Kits
reload (D329). The add-after-boot stays as a fallback, now through the
console's websocket, and is a finding when Kits does not load again.
