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.

+## Usage
+
+```toml
+[dependencies]
+mytheclipse-http = "0.2"
+```
+
+### Client with timeout
+
+```rust
+use mytheclipse_http::HttpClient;
+use std::time::Duration;
+
+#[tokio::main]
+async fn main() -> Result<(), reqwest::Error> {
+    let client = HttpClient::new().with_timeout(Duration::from_secs(10));
+    let resp = client.get("https://httpbin.org/get").await?;
+    println!("status: {}", resp.status());
+    Ok(())
+}
+```
+
+### Server (axum)
+
+```toml
+[dependencies]
+mytheclipse-http = { version = "0.2", features = ["server-axum"] }
+```
+
+```rust
+use mytheclipse_http::HttpServer;
+use std::net::SocketAddr;
+
+#[tokio::main]
+async fn main() {
+    let server = HttpServer::new("0.0.0.0:3000".parse().unwrap());
