* Enable multitenancy support and normalize tenant ID handling.
- Activate multitenancy in `Program.cs`.
- Introduce `NormalizeTenantId` method for consistent tenant ID usage.
- Update tenant-related classes and features to support normalization logic.
* Add ADR for adopting empty string as the default tenant ID
- Standardized the tenant ID for the default tenant to use an empty string (`""`) instead of `null`.
- Documented the rationale and migration considerations in ADR 0007.
- Updated ADR table of contents and graph for new entry.
* Apply suggestion from @sfmskywalker
* Update doc/adr/graph.dot

* Normalize spacing and improve readability in `Program.cs`. Fix multitenancy condition formatting.
* Fix ADR numbering and update TOC
* Add ADRs for flowchart execution model, tenant deletion event, merge modes, and default tenant ID
- Introduced ADR 0005: Token-centric flowchart execution model for improved loop and join handling.
- Added ADR 0006: Tenant Deleted event for distinct handling of tenant removal.
- Documented ADR 0007: Explicit merge modes for flowchart joins, improving reliability and configurability.
- Included ADR 0008: Standardization of empty string as the default tenant ID for consistency and clarity.
* Add unit tests for tenant ID normalization and multitenancy pipeline invoker
- Added comprehensive unit tests for tenant ID normalization to ensure consistent handling of null, empty, and valid IDs.
- Introduced tests for the multitenancy pipeline invoker covering various tenant resolution scenarios.
- Updated solution to include new unit testing projects for `Elsa.Tenants` and `Elsa.Common`.
* Update unit tests for `ActivityConstructionResult`
- Refactor test parameterization to verify `HasExceptions` property more explicitly.
- Simplify exception creation logic in helper methods.
- Improve test assertions by combining act and assert phases where applicable.
* Enable configuration-based multitenancy with tenant-specific settings
- Introduced a configuration-based tenant provider to streamline tenant initialization and customization.
- Added tenant ID handling filters to ensure tenant ID is applied and filtered automatically.
- Deprecated the `CommonPersistenceFeature` in favor of modular persistence feature extension.
* Update database indexes to include `TenantId` for multitenancy support
- Added `TenantId` to unique constraints on `Triggers` table across all EFCore providers.
- Adjusted index names to reflect the updated constraints.
- Updated trigger configuration to ensure uniqueness includes `TenantId`.
* Add tenant filtering to `DefaultWorkflowDefinitionStorePopulator`
- Introduced `ITenantAccessor` to support tenant-specific filtering of workflow definitions.
- Updated logic to skip workflows not matching the current tenant.
* Update doc/adr/toc.md

* Remove `CommonPersistenceFeature` as it has been deprecated
* Add tenant-specific filtering to workflow import logic in `DefaultWorkflowDefinitionStorePopulator`
* Replace hardcoded tenant ID with `Tenant.DefaultTenantId` in integration tests
* Update database indexes and migration logic to support `TenantId` for multitenancy
- Added `TenantId` to unique constraints on the `Triggers` table and updated index names.
- Included logic to drop outdated indexes without `TenantId` during migration.
- Adjusted tests to account for `TenantId` in workflow identity and indexing scenarios.
* Remove `TenantId` from workflow identity construction in concurrent trigger indexing tests
* Introduce `SelectiveMockLockProvider` for precise lock mocking in tests
- Added `SelectiveMockLockProvider` to allow targeted lock mocking without affecting unrelated background operations.
- Updated test services to use `SelectiveMockLockProvider` in place of `TestDistributedLockProvider`.
- Refactored `DistributedLockResilienceTests` to support selective mocking for deterministic and reliable assertions.
* Update Elsa.sln

* Normalize tenant ID handling in `DefaultWorkflowDefinitionStorePopulator` for consistent filtering
* Refactor `TenantResolverResult` to support explicit resolved/unresolved state handling
- Updated `TenantResolverResult` to include an explicit `_isResolved` property.
- Adjusted `ResolveTenantId()` and `IsResolved` logic for improved clarity and robustness.
- Simplified tenant resolution invocation in `TenantResolverBase`.
- Removed redundant normalization in `DefaultTenantResolverPipelineInvoker`.
* Normalize tenant ID handling in `DefaultWorkflowDefinitionStorePopulator` and `ClrWorkflowsProvider`.
* Refactor `DefaultWorkflowDefinitionStorePopulatorTests`: streamline object initializations and add tenant-specific test coverage for `PopulateStoreAsync`.
