docs: add self-hosted production readiness roadmap

[weroperking]

Summary

• Comprehensive audit and gap analysis scoped specifically for self-hosted production — teams running BetterBase on their own infrastructure.
• Strips away SaaS/unicorn-scale concerns that do not apply to single-tenant self-hosted deployments.
• Identifies real blockers across 4 pillars: Security, Stability, Operations, and Multi-Instance Scaling.
• Provides a prioritized 3-phase implementation plan (7 weeks total).

Key Findings

Pillar	Real Blockers
Security	Rate limiting on auth endpoints (table exists, middleware missing), API key scope enforcement, HTML escaping in device verify, security headers
Stability	Transactional migrations, deep health checks, graceful shutdown, E2E tests
Operations	Backup automation, Prometheus metrics, upgrade documentation
Multi-Instance	Redis bridge for WS + rate limits across replicas, K8s manifests

What is Excluded (SaaS-scale items)

Read replicas, multi-language SDKs, React-free client refactor, API versioning, OpenAPI generation, chaos engineering, circuit breakers, Terraform/Pulumi IaC, one-click cloud deploy scripts, MFA for admins, IP allowlisting, app-level column encryption, RS256 JWT, Neon CDC replacement.

Summary by CodeRabbit

Documentation

• Added comprehensive production readiness roadmap for self-hosted deployments, detailing security requirements (rate limiting, API key scope, security headers), reliability specifications (health checks, graceful shutdown, testing), operational guidance (backup/recovery, metrics, logging, upgrades), and scaling considerations with acceptance criteria.

Walkthrough

Adds a new documentation page defining production readiness criteria for self-hosted BetterBase deployments. Covers required security controls, reliability guarantees, operational requirements, and multi-replica scaling specifications with explicit scope boundaries excluding SaaS enterprise audit items.

Summary

Production Readiness Documentation docs/guides/production-readiness-roadmap.md

New 332-line guide establishing must-have security controls (rate limiting, API key scoping, HTML escaping, CSP, security headers), reliability requirements (transactional migrations, distinct health endpoints, graceful shutdown, e2e testing), operational guidance (backup/recovery, Prometheus metrics, log aggregation, upgrade process), and multi-replica scaling specifications (Redis-backed shared state, Kubernetes manifests, Helm chart).
