[P0.52] Coordinated launch (HN + Twitter + ProductHunt + Reddit)

[EmersonBraun]

User Story

As a maintainer, I want lançamento coordenado (HN + Twitter + ProductHunt + Reddit) planejado como evento único quando Phase 0 terminar — uma chance só, tem que ser com tudo pronto.

Context

Derivada do Phase 0 PRD #211 — story #52.
Plano de execução: PHASE-0-EXECUTION-PLAN.md

Definition of Done

• Implementation
• Testes/validação
• Documentation updated
• Changeset (se aplicável)
• PR aprovado e merged

This is a strategic / business task that an automated coding agent cannot execute (requires human action: legal filings, vendor relationships, hiring, marketing, organizational decisions). Leaving open for the maintainer team to schedule.
