ntkit v2.2.0

Two additions lead this release.

Launch videos. /package-nt now makes the launch video itself. brag is vendored inside it, so a fresh install needs no other skill. It has two modes: demo, 15–25 s of the product in use for people who will install it, and promo, 35–45 s of one headline per thing the product does, for leadership and non-technical viewers. Every video gets a settled poster baked into frame 0 and a fresh-context stranger test on what and who. The 43-second promo attached below was made this way.

Disk cleanup. /reclaim-nt scans with disktree-cli. Sizes are what deleting gives back. Findings come in two tiers, so the model judges only what may be someone's only copy: weights, worktrees with their git state, stale experiments, old archives. Build output and caches skip the judgment. Removal goes to the Trash only, one named finding at a time, through tested guards.

Also in this release

• /demo-nt hosted mode: serve the demo from your laptop through a named tunnel, sign in as fictional personas, and pass an anonymous probe of every public hostname before the link is shared. It keeps a presenter playbook in plan/demo-protocol.md.
• A test bench: tests/run.sh (free, seconds) and evals/run.sh (one model run per case).
• A contrast gate on social cards, caption-first launch drafts, and a HERO_FLOW storyboard from /guide-nt.

Known gap: the /demo-nt probe stop-line has no eval case, because it needs a live tunnel.

Credits for disktree and brag are in the README. Full detail: CHANGELOG.md.
