feat: add IP-based rate limiting for unauthenticated token endpoint#58
Conversation
Add TokenRateLimitMiddleware to protect POST /v1/token from credential stuffing and brute force attacks using per-IP throttling with token bucket algorithm and automatic cleanup of stale limiters. New configuration: - RATE_LIMIT_TOKEN_ENABLED (default: true) - RATE_LIMIT_TOKEN_REQUESTS_PER_SEC (default: 5.0) - RATE_LIMIT_TOKEN_BURST (default: 10) Token endpoint now returns 429 with Retry-After header when per-IP limits are exceeded, using stricter defaults than authenticated endpoints to reduce attack surface on unauthenticated paths. Documentation updates include v0.7.0 release notes, upgrade guide, operator runbooks (quick card, incident decision tree, first 15 minutes playbook, trusted proxy reference), persona landing pages, day-0 onboarding walkthroughs, Phase 3/4 roadmaps, docs quality KPIs, postmortem feedback loop, versioned examples index, known limitations, and comprehensive updates to API docs, environment variable reference, troubleshooting, monitoring queries, and smoke tests. CI improvements add release image tag consistency guard and expanded docs validation workflow. Updated all pinned Docker examples from v0.6.0 to v0.7.0.
