0.5.0 - 2026-03-06

Added

• Observability instrumentation: tracing spans on RPC handlers, job workers, and cron ticks with structured fields; Prometheus-style metrics for request count, latency, and queue depth; slow query logging with configurable threshold; startup summary banner
• Consistent query routing via #[forge::query(consistent)] attribute to force reads from primary, bypassing replicas for read-after-write consistency
• Health-aware replica selection: background monitor pings replicas every 15s, automatically skips unhealthy replicas and falls back to primary
• Workload-isolated connection pools (pools.default, pools.jobs, pools.observability, pools.analytics) with independent size and timeout configuration
• Coalesced real-time subscriptions: identical query subscriptions share a single re-execution instead of running per-client
• Hybrid rate limiting combining in-memory token bucket with PostgreSQL-backed sliding window for cluster-wide consistency
• Cluster-aware cache invalidation via forge_invalidations table so nodes only re-execute queries affected by changes on other nodes
• forge-idiomatic-engineer Claude Code skill shipped with scaffolded projects for AI-assisted development

Changed

• Removed 20 direct dependencies by reimplementing minimal usages inline (async-stream, hex, regex, regex-lite, walkdir, darling, dialoguer, indicatif, hostname, arc-swap, sysinfo, slab, smallvec, once_cell, futures, axum-extra, tonic, prost, hyper, and gRPC features from opentelemetry-otlp)
• Switched OTLP telemetry transport from gRPC (port 4317) to HTTP (port 4318), eliminating duplicate transitive dependency trees (axum 0.7, tower 0.4, matchit 0.7)
• Dropped bundled AGENTS.md from project templates in favor of the installed skill
