refactor(services,stores): effectify zome services and stores with R&O DI pattern

[Soushi888]

Intent

Wire the Effect-TS infrastructure (errors, schemas, utilities) already in place to the actual services and stores. Before this PR, all three zome services used raw Promise-based class methods with try/catch, and all three stores used a 4-state string enum for loading state. The Effect layers (wrapZomeCallWithErrorFactory, withLoadingState, store-helpers) were implemented but not consumed.

Changes

HolochainClientService: adds HolochainClientServiceTag (Context.Tag) and HolochainClientServiceLive (Layer.succeed wrapping the singleton) — the DI entry point that services depend on.

Zome services (person, resource, governance): converted from Promise-based class methods to the R&O Context.Tag/Layer pattern:

• Interface defines each method as E.Effect<T, DomainError>
• ServiceTag extends Context.Tag
• ServiceLive: Layer.effect(Tag, E.gen(function* () { const client = yield* HolochainClientServiceTag; ... }))
• ServiceResolved pre-wires HolochainClientServiceLive for convenient use in stores

Stores (person, resource, governance): converted from ad-hoc async/try-catch to the R&O factory pattern:

• Store factory returns E.Effect<Store, never, ServiceTag> via E.gen
• Factory yields the service via yield* ServiceTag, removing all direct service imports
• Store methods use withLoadingState from store-helpers; loading state migrated from 4-state enum to boolean isLoading + string|null errorMessage
• Store instance instantiated via pipe(createStore(), E.provide(ServiceResolved), E.runSync)

Decisions

Loading state model change: The previous 4-state string enum ('idle' | 'loading' | 'success' | 'error') was replaced with boolean isLoading + string|null errorMessage. Rationale: the 4-state model required components to match on strings and carried no additional information beyond what the two booleans express. The Effect error channel already carries typed error information; the store's job is only to surface whether an operation is in-flight (isLoading) and whether the last operation left an error message (errorMessage). This simplifies both the store implementation and consumer components.

Error context constants: Added 8 missing constants to GOVERNANCE_CONTEXTS in error-contexts.ts (UPDATE_COMMITMENT, GET_COMMITMENTS_BY_PROVIDER, GET_COMMITMENTS_BY_RECEIVER, GET_EVENTS_BY_TYPE, GET_EVENTS_IN_TIME_RANGE, GET_RESOURCE_FLOW, CREATE_DISPUTE, VOTE_ON_DISPUTE) and updated all mismatched wz() calls in the governance service to use the correct contexts.

How to test

bun run --filter ui check   # 0 errors, 0 warnings

Documentation

Updated documentation/IMPLEMENTATION_STATUS.md to mark the Effect-TS service layer (#7) as complete (was ❌ Not started in both the UI Components list and the Phase 2 progress table).

🔴 REVIEW.md violation: DOCUMENTATION_INDEX.md not updated after feature milestone completion

Per REVIEW.md §6 (Documentation Currency), when a feature milestone is completed, both documentation/IMPLEMENTATION_STATUS.md and documentation/DOCUMENTATION_INDEX.md must be updated. This PR marks the Effect-TS service layer as ✅ Complete at documentation/IMPLEMENTATION_STATUS.md:181 and documentation/IMPLEMENTATION_STATUS.md:244, but documentation/DOCUMENTATION_INDEX.md was not modified. The REVIEW.md mapping table explicitly states: "Feature milestone completed (phase advancement) → documentation/IMPLEMENTATION_STATUS.md, documentation/DOCUMENTATION_INDEX.md".

Prompt for agents

The PR marks 'Effect-TS service layer' as complete in IMPLEMENTATION_STATUS.md (line 181 and line 244), but per REVIEW.md rule 6, documentation/DOCUMENTATION_INDEX.md must also be updated when a feature milestone is completed. Open documentation/DOCUMENTATION_INDEX.md and add or update the entry for the Effect-TS service layer to reflect its completion in PR #97. The exact location in DOCUMENTATION_INDEX.md depends on how the file is structured — look for any section referencing the UI service layer, frontend architecture, or issue #7.
