Propylea v0.3.0: Speculative Hedged Tournament Racing

🌟 Propylea v0.3.0: Speculative Hedged Tournament Racing

• Active-Active Speculative Hedged Racing: Integrated sovereign hippodrome tournament engine under the hedged-racing feature. Replaces naive round-robin with microsecond fastest-horse concurrency.
• Adaptive P99 Tail-Latency Elimination: Automatically dispatches to the leader, hedged speculatively by secondary upstreams when leader stalls beyond the EWMA window. Losers are aborted in microseconds with zero memory leak.
• Method-Aware HTTP Idempotency Policy: Concurrent hedged racing on idempotent methods (GET, HEAD, OPTIONS, TRACE) combined with safe single-flight execution and instantaneous failover on mutating verbs (POST, PUT, DELETE, PATCH).
• Multi-Upstream Route Topology: Declarative upstreams = [...] pool configuration alongside standalone upstream.
• Static Musl Binaries with Hedged Racing: Pre-compiled multi-platform release binaries natively include Hippodrome tournament racing across Linux, macOS, and Windows.
• Cryptographic Provenance: Deterministic SHA-256 digests and OpenPGP detached signatures signed under Sovereign Release Key 4E428019A109578B (SOVEREIGN-SIGN-01).
