feat: implement replicant state synchronization for commentary, players, scoreboard, and graphics settings

- Added a new service for synchronizing state with replicants in `replicant-state-service.ts`.
- Refactored commentary store to utilize the new synchronization service.
- Created a new graphics settings store that syncs with replicants.
- Introduced a packs store for managing installed packs and their states.
- Updated players and scoreboard stores to use the new synchronization service.
- Created shared services for managing replicated state in graphics components.
- Refactored existing components to use the new shared services for replicant state.
- Added normalization and default values for commentary, graphics settings, players, and scoreboard.
- Improved type safety and organization in shared domain files for better maintainability.

+# Phase 2 Summary
+
+## Scope
+
+Executed the state and replicants phase only.
+
+This phase focused on isolating state logic, normalizing Pinia stores, encapsulating browser-side replicant access, and moving side effects behind services without changing UX, visual design, overlay CSS, or public NodeCG contracts.
+
+## Completed
+
+- Added pure state/domain modules:
+  - `src/shared/domain/scoreboard`
+  - `src/shared/domain/commentary`
+  - `src/shared/domain/graphics`
+  - `src/shared/domain/players/state.ts`
+  - `src/shared/domain/packs/characters.ts`
+- Moved normalization and pure state transitions out of dashboard stores.
+- Replaced direct dashboard replicant imports with `src/dashboard/services/replicant-state-service.ts`.
+- Added `useGraphicsSettingsStore` and moved dashboard graphics skin writes through the store.
+- Reworked scoreboard, players and commentary stores to use shared domain normalizers and service-based replicant sync.
+- Replaced the pack registry singleton composable with a normalized `usePacksStore`.
+- Moved pack replicant listeners and NodeCG pack messages into `src/dashboard/services/pack-service.ts`.
+- Removed Vue reactivity and mutable pack registration from `src/shared/fighting-characters.ts`.
+- Modeled installed pack manifests as explicit store state instead of hidden module state.
+- Centralized registry auto-refresh timer in the packs store.
+- Routed integration NodeCG messages through `src/dashboard/services/integration-message-service.ts`.
+- Added `src/graphics/shared/services/replicated-state.ts` so graphics read replicants through a service layer.
+- Removed the redundant `src/dashboard/stores/store-sync.ts`.
+
+## Preserved
+
+- Public replicant names were unchanged.
+- Public message names were unchanged.
+- Existing dashboard UX was preserved.
+- Overlay markup, CSS, positioning and animation logic were not intentionally changed.
+- The existing `usePackRegistry` import path remains as a compatibility wrapper over the packs store.
+- The legacy `src/shared/fighting-characters.ts` path remains as a compatibility export, but no longer owns mutable runtime state.
+
+## Realtime Flow After This Phase
+
+```text
+schemas
+  -> nodecg/browser
+  -> dashboard services / graphics services
+  -> Pinia stores or overlay computed state
+  -> components
+```
+
+Pack runtime flow:
+
+```text
+pack replicants
+  -> pack service
+  -> packs store
+  -> pack registry compatibility composable
+  -> game / character UI
+```
+
+## Verification
+
+- `pnpm.cmd exec vue-tsc -p tsconfig.browser.json --noEmit`: passed.
+- `pnpm.cmd exec tsc -b tsconfig.extension.json --pretty false`: passed.
+- `pnpm.cmd exec eslint`: passed with 0 errors and existing Vue formatting warnings.
+- `pnpm.cmd run build`: passed.
+- Searched dashboard, graphics and shared for direct NodeCG/message/replicant imports:
+  - remaining browser NodeCG access is contained in services and `nodecg/browser`.
+  - direct component/view replicant imports were removed.
+- Searched for `any` in touched runtime areas:
+  - no new TypeScript `any` usage was added.
+
+## Notes and Limits
+
+- This phase did not split large views like `Players.vue` or `Settings.vue`.
+- This phase did not refactor overlay internals beyond replacing direct replicant imports with a read service.
+- This phase did not rewrite extension-side `pack-manager.ts`.
+- This phase did not rename public messages to the future canonical names; compatibility was preserved.
+- Existing Vue lint warnings remain formatting-only and were not addressed because they are outside this phase.
+
+## Remaining For Later Phases
+
+- Controlled rewrite of `pack-manager.ts`.
+- Full split of `useIntegration` into provider clients, OAuth client, temporary players and import modules.
+- Divide `Players.vue` and `Settings.vue`.
+- Extract overlay view models and visual helpers after visual baseline.
+- Add tests for pure normalizers and pack state derivations.
