Implementation Spec: Round 16 — COMPLETE

Goal

Make the round-7-15 abstractions actually usable — a single, runnable, wired example showing high-level primitives composing together.

crates/mytheclipse/examples/high_level.rs

• One realistic flow demoing, wired together:
  1. RuntimeConfig::auto() — auto thread/core sizing from host CPU
  2. parallel_map — bounded fan-out + AggregateError
  3. RetryExt — ergonomic .retry() on a Future
  4. ShutdownGuard — RAII exactly-once cleanup
  5. AutoReconnectPool — self-healing resource pool (dead value replaced)
  6. AutoMetricsServiceBuilder — auto latency/outcome metrics
• Run: cargo run -p mytheclipse --features full --example high_level

Verified Output (real run, 8-core host)

1. RuntimeConfig::auto() -> worker=8, blocking=12, compute=8, io=4
2. parallel_map -> [10, 20, 30, 40, 50]
3. RetryExt with 4 attempts -> 42
4. ShutdownGuard fired 1x (exactly-once, even on unwind)
5. AutoReconnectPool first acquire -> 999
6. AutoMetrics -> 1 counters, 1 histograms
