feat: add 4 new crates (queue, tracing, http, cli) + enhancements to existing crates

New crates:
- mytheclipse-queue: unified job queue with WorkerPool, retry/backoff, DLQ
  Backends: in-memory (default), Redis, NATS, PostgreSQL
- mytheclipse-tracing: tracing subscriber layers with env filter + OTLP/Jaeger export
- mytheclipse-http: HTTP client/server with timeout + tracing, axum server
- mytheclipse-cli: CLI framework with clap derive, built-in subcommands

Enhancements to existing crates:
- mytheclipse-core: SemaphorePool, LeaderElection, HealthRegistry/HealthCheck
- mytheclipse-cache: AutoRefreshCache (bg refresh on miss), CacheMetrics
- mytheclipse-config: ConfigSchema for JSON Schema generation
- mytheclipse-storage: MultipartUploadDriver trait
- mytheclipse-crypto: PASETO v4.local token support

All features compile with --all-features; tests + clippy pass clean.
