release: prepare the AfterHook v0.1.0 demo

[fabiorosa]

What changed

• package one Docker image with isolated API, worker, and destination processes
• serve the compiled React console from the public API origin
• define a zero-cost Render web + Key Value Blueprint with Neon PostgreSQL
• capture deterministic event-list, failed-attempt, and safe-retry evidence
• document free-tier cold-start and disposable-Redis limits

Why

WOP-305 needs a truthful public demo without recurring portfolio hosting cost. Vercel functions cannot host the persistent BullMQ worker, so the three Node.js processes share one free Render web container while preserving logical boundaries.

Validation

• 53 unit and HTTP tests passed
• 24 PostgreSQL/Redis integrations passed
• 11 Chromium scenarios passed; Windows teardown outlived the local command after all assertions
• targeted evidence walkthrough passed in 6.6 seconds
• production runtime audit reports zero vulnerabilities
• Docker image built successfully
• co-located container reported a healthy worker, served the console, and delivered a fictional event

Remaining gate

Connect the Blueprint to free Render and Neon accounts, verify the hosted journey, recapture hosted evidence, and publish v0.1.0.
