Ship the 3D-first v0.1.4 growth funnel

[mrcha033]

Summary

• put the audited generated 3D assembly in the first README screen and reproducible 20-second demo
• replace stale source-only language with the clean-smoked PyPI quickstart
• align v0.1.4 package, plugin, repository, and launch metadata
• add a measured 30-day traction plan and real newcomer contribution path
• retain the candidate-versus-fabrication qualification boundary throughout

Verification

• python3 scripts/refresh_demo.py --check
• python3 scripts/refresh_demo.py --verify-release-evidence
• uv run ruff check src/ tests/
• python3 -m pytest -q tests/test_release_metadata.py
• clean Python 3.11 wheel install, version assertion, hw --help, project creation, and validate-spec
• clean Python 3.11 release metadata plus 3D/review bundle test set
• uv build produced the 0.1.4 wheel and source distribution

Evidence boundary

The rendered RP2040 board remains a CAD candidate. This change does not claim fabrication, bring-up, sourcing qualification, or physical qualification.
