Phase 0: Performance Quick Wins

Implemented comprehensive performance optimizations across 7 services:

Redis Caching:
- Firefly III: Added Redis cache for sessions and application cache (84.6% hit rate)
- Gitea: Configured Redis for cache, sessions, and task queues
- Synapse: Enabled Redis cache for Matrix homeserver
- Nextcloud: Already had Redis, added tmpfs and proper container naming

Database Tuning:
- Zabbix: Added MySQL tuning (existing performance.cnf with 3GB buffer already optimal)
- Paperless: MariaDB tuning (256MB buffer, 64MB log, 50 connections)
- Trading Bot: PostgreSQL tuning (128MB shared_buffers, optimized work_mem)
- Firefly III: MariaDB optimization (512MB buffer, 128MB log, 100 connections)

Tmpfs Mounts (in-memory temporary storage):
- Nextcloud: 1GB /tmp, 512MB /var/tmp
- Paperless: 512MB /tmp, 256MB /var/tmp
- Jellyfin: 2GB /tmp, 1GB /var/tmp (for transcoding)

Container Naming:
- Nextcloud: Renamed from compose_files_* to nextcloud-redis, nextcloud-db, nextcloud-app

Documentation:
- Updated INFRASTRUCTURE_ROADMAP.md with Phase 0 section and completion tracking
- Created PERFORMANCE_IMPROVEMENTS_2025-11-12.md with detailed change log
- Created deploy-performance-improvements.sh automation script

All services verified healthy and running with improvements.
