Add KineticOS continuation-fleet example (agent fleet built on SuperPlane)

[sahielbose]

What this is

A self-contained example under examples/kineticos-continuation-fleet/ —
KineticOS, a project built on SuperPlane: a CAD image of a broken
industrial machine comes in → a fleet of agents identifies the fault, generates
a new 3D-printable CAD file, validates it, and resumes production, with
SuperPlane gating every phase.

Maintainers: this is a downstream app example, not a platform change. It
lives entirely under examples/, adds nothing to your build/CI, and touches no
existing files. If you'd rather take only the workflow template, the one file
worth upstreaming is the Canvas — it drops into templates/canvases/ with
metadata.isTemplate: true per docs/contributing/templates.md. I'm glad to
reshape this PR down to just that. See SUBMISSION.md in the folder.

Highlights — the Canvas

infra/superplane/kineticos-fleet.canvas.yaml (34 nodes / 40 edges) exercises a
lot of SuperPlane in one real workflow:

• Parallel fan-out + merge — six perception agents run concurrently from
  the ingest trigger; a merge barrier fuses them.
• Gate pattern (×4) — each phase ends in http (evaluate-gate) → if
  (decision == "proceed") → approval (human gate); rejections route to halt.
• Conditional branch — if chooses an off-the-shelf substitute vs. a
  generated continuation part.
• http executors call the app's per-agent endpoints; annotations
  document each section on-canvas.

A .local.canvas.yaml variant points executors at host.docker.internal:3000
for a containerized SuperPlane calling the app on the host.

The rest of the folder

The downstream app it drives — Next.js HTTP executors (src/app/api/agents/**,
src/lib/contract.ts), the node→agent map / loader / offline rehearsal
(infra/superplane/{README,apply.sh,smoke.sh}), and project docs. The
TypeScript is illustrative (not platform code; not built by your CI).
