v0.1.0 — zero-copy fork

First release.

What

• zero-copy fork: route fork through Session.prepare(seedSource:'persistence') so the child session reuses deep-frozen immutable event references instead of deep-copying the whole log — 344ms → 19ms on an 18.2MB / 20k-event session.
• fast initFor: PersistenceCoordinator.initFor's structuredClone(seed) replaced by frozen-reference reuse (135ms → ~0ms), guarded by an rc.6 source-signature check.
• Three-layer fallback: capability probe → try/catch to native → config switch; dispose fully restores originals.
• Monitoring API: POST /dsh-fork-perf/api/{stats.get,stats.reset,config.get,config.set}.
