[help wanted] Serialization migration tool (shadow→dual-write→cutover CLI)

[DavidHLP]

Goal (v0.2.0, P1)

Migrate legacy Spring-native caches (GenericJackson2JsonRedisSerializer / JdkSerializer) to ResiCache's {version,payload} envelope (ADR-0003) without a full-miss cutover.

Scope

• CLI: shadow-read → dual-write → cutover phases.
• R31 SerializationPreFlightProbe is the diagnostic down-payment (detects non-envelope values at startup).

Refs

• ADR-0003, guide §v0.2.0, wiki/modules/serialization.md, wiki/modules/configuration.md (probe-enabled)
