0.2.1 (#25)

* perf: Database optimization for query speed improvements (#6)

  Implements comprehensive database optimizations to achieve sub-100ms query latency:

  ## Index Optimization
  - Add composite indexes for common query patterns:
    - idx_logs_project_level_time (project + level filtering)
    - idx_logs_project_service_time (project + service filtering)
    - idx_logs_project_service_level_time (combined filtering)
    - idx_logs_project_errors (partial index for error logs)
  - Remove duplicate index (idx_logs_project_time)

  ## TimescaleDB Continuous Aggregates
  - Add logs_hourly_stats for dashboard timeseries (10-50x faster)
  - Add logs_daily_stats for historical analytics
  - Dashboard service now uses pre-computed aggregates

  ## Compression Policy
  - Change compression from 7 days to 1 day for faster storage savings
  - Expected 90% storage reduction for data >1 day old

  ## PostgreSQL Tuning (docker-compose)
  - Configure parallel query settings (max_parallel_workers=8)
  - Tune shared_buffers, work_mem, WAL settings
  - Enable slow query logging (>100ms)

  ## Connection Pooling
  - Environment-based pool sizing (5/10/20 connections)
  - Statement timeout protection (30s prod, 60s dev)
  - Slow query logging in application layer
  - Add getPoolStats() for monitoring

  ## Admin Health Endpoint
  - Add pool statistics (totalConnections, idleConnections, waitingRequests)
  - Pool health affects overall health status

  ## Verified Performance
  - Smoke test: 180/180 checks, 3.28ms avg, 0% errors
  - Ingestion test: 722,890 logs, 7.40ms P95, 0% errors
  - EXPLAIN ANALYZE: 0.28-0.71ms per query with new indexes

  Closes #6

* feat: Implement Redis caching layer for query results (#7)

Adds comprehensive Redis caching to minimize database load and improve response times:

  - CacheManager utility with type-safe keys, configurable TTLs, and hit/miss tracking
  - Session validation caching (30 min TTL, invalidated on logout)
  - API key verification caching (60 sec TTL, async last_used updates)
  - Query result caching with deterministic keys (60 sec TTL)
  - Trace and aggregation caching (5 min TTL)
  - Automatic cache invalidation on log ingestion
  - Admin API endpoints for cache stats and management:
    - GET /api/v1/admin/cache/stats
    - POST /api/v1/admin/cache/clear
    - POST /api/v1/admin/cache/invalidate/:projectId
  - Configuration via CACHE_ENABLED and CACHE_TTL environment variables

  Expected performance improvements:
  - Session validation: ~30x faster (cache hit)
  - API key verification: ~20x faster (cache hit)
  - Query results: ~10x faster (cache hit)
  - Aggregations: ~50x faster (cache hit)

  Closes #7

* fix: Update navigation paths to include /dashboard prefix

* chore: Bump version to 0.2.1 and update related references

v0.2.0

Opentelemetry implementation (#14)

* feat: Add OpenTelemetry support with OTLP routes and log transformation

* feat: Update trace_id handling to accept any string format

* feat: Implement OpenTelemetry trace ingestion with API routes and database support

* feat: Add service dependencies visualization and related API support

* feat: Enhance span selection with keyboard accessibility and optimize service dependencies query

* feat: Add factories for creating test spans and traces with comprehensive attributes

* ● feat: Optimize OTLP ingestion and fix frontend UX issues

  Backend:
  - Add sanitizeForPostgres() to strip null bytes from OTLP strings
  - Optimize span insertion with batch INSERT using UNNEST (100-1600x faster)
  - Increase Fastify body limit to 10MB for large OTLP batches

  Frontend:
  - Fix Service Map card padding in /traces page
  - Fix Start Time text wrapping in trace details page
  - Fix search page not loading logs when navigating with traceId param
  - Add debounced auto-search for message and trace ID inputs

* Bump to 0.2.0
