template: drop prescriptive how-to, add module-builder requirement

- Trim the cross-platform bullet: state the outcome (works on both
  platforms) rather than prescribing the implementation. The earlier
  wording told builders how to structure their flake, which isn't the
  template's job.
- Add a new Supportability bullet pointing builders at
  logos-module-builder + the Logos tutorial. Hand-rolled module flakes
  are how cross-platform packaging breaks in the first place; the
  shared builder already handles Mach-O vs ELF correctly.

-> - The submission builds and runs end-to-end on both **macOS (Apple Silicon)** and **Linux (x86_64)**. The demo script must succeed without modification on both platforms from a clean clone. If a component is genuinely platform-bound (e.g. Mach-O install-name fixup), the flake/build system must conditionally skip it on the other platform rather than fail evaluation.

Hand-rolled module flakes are discouraged: cross-platform packaging (Mach-O install names, ELF RPATH, etc.) lives in the shared builder so individual modules don't have to re-solve it.
 > - End-to-end integration tests run against a LEZ sequencer (standalone mode) and are included in CI.
 > - CI must be green on the default branch.
 > - A README documents end-to-end usage: deployment steps, program addresses, and step-by-step instructions for interacting with the program via CLI and Basecamp app.
