[Service] Effect-TS Layer 1: Connection service + zome service wrappers

[Soushi888]

Summary

Implements Layer 1 (Service) base — the Effect-native connection service with exponential backoff retry and the three domain service tags wrapping all coordinator zome externs.

Partially implemented by #97: HolochainClientServiceTag + HolochainClientServiceLive (singleton DI entry point) and all three zome service tags/layers (PersonServiceTag/PersonServiceLive/PersonServiceResolved, ResourceServiceTag/ResourceServiceLive/ResourceServiceResolved, GovernanceServiceTag/GovernanceServiceLive/GovernanceServiceResolved) are complete. All service methods already return E.Effect<T, DomainError>. Remaining scope: ConnectionServiceTag with exponential backoff retry and unit tests per service.

Scope

• services/HolochainClientService.svelte.ts — update ZomeName type to 'zome_person' | 'zome_resource' | 'zome_gouvernance'
• services/connection.service.ts — ConnectionServiceTag + ConnectionServiceLive with exponential backoff (ported from R&O)
• services/zomes/person.service.ts — PersonServiceTag + PersonServiceLive wrapping all zome_person externs ✅ done by refactor(services,stores): effectify zome services and stores with R&O DI pattern #97 (includes PersonServiceResolved)
• services/zomes/resource.service.ts — ResourceServiceTag + ResourceServiceLive wrapping all zome_resource externs ✅ done by refactor(services,stores): effectify zome services and stores with R&O DI pattern #97 (includes ResourceServiceResolved)
• services/zomes/governance.service.ts — GovernanceServiceTag + GovernanceServiceLive wrapping all zome_gouvernance externs ✅ done by refactor(services,stores): effectify zome services and stores with R&O DI pattern #97 (includes GovernanceServiceResolved)

Acceptance Criteria

• All zome_person, zome_resource, zome_gouvernance externs have a typed service method — done by refactor(services,stores): effectify zome services and stores with R&O DI pattern #97
• Each ServiceLive composes correctly with HolochainClientServiceTag via Layer.effect — done by refactor(services,stores): effectify zome services and stores with R&O DI pattern #97
• ConnectionServiceTag with exponential backoff retry implemented and wired
• Unit tests per service using mock HolochainClientServiceTag
• bun run check and bun run test pass
