* Initial plan
* Increase ActivityNodeId column max length from 450 to 1024 to fix truncation for deeply nested workflows
Add HasMaxLength(1024) for ActivityNodeId on ActivityExecutionRecord and
WorkflowExecutionLogRecord entities. Create V3_7 migrations for all 5
database providers (SqlServer, MySql, PostgreSql, Sqlite, Oracle).
Co-authored-by: sfmskywalker <938393+sfmskywalker@users.noreply.github.com>
* Use NVARCHAR(MAX) and equivalent unlimited column types for ActivityNodeId
Update V3_6 migrations to change ActivityNodeId from fixed-length columns
to unlimited types: nvarchar(max) for SQL Server, longtext for MySQL,
NCLOB for Oracle. PostgreSQL (text) and SQLite (TEXT) already used
unlimited types. Drop ActivityNodeId indexes on both ActivityExecutionRecords
and WorkflowExecutionLogRecords tables since unlimited columns cannot be
indexed. Remove HasIndex for ActivityNodeId from Configurations.cs.

- PostgreSQL: DROP INDEX IF EXISTS (native support)
- SQLite: DROP INDEX IF EXISTS (native support)
- MySQL: information_schema.statistics check with PREPARE/EXECUTE
- Oracle: PL/SQL BEGIN...EXCEPTION WHEN OTHERS (SQLCODE -1418)

* Adds activity execution call stack support
Implements a call stack mechanism to track the execution chain, enabling visibility into the invocation hierarchy.
Introduces new fields to scheduling models and runtime contexts to store call stack information.
Includes EF Core migrations for various database providers to support new columns in `ActivityExecutionRecords`.
Provides an API to query and reconstruct the call stack for a given activity execution.
* Refactor: Replace `PagedCallStackResult` with `Page<T>` for execution chain pagination
* Remove ambient scheduling scope logic and related methods
Simplifies scheduling logic by removing ambient scope mechanisms, refactoring scheduling context handling, and updating affected classes accordingly.
* Add `GetCallStackAsync` to `IActivityExecutionsApi` for querying activity execution call stack
* Add new properties to `ActivityExecutionRecord` for scheduling and execution tracking
Introduce fields for aggregated fault count, scheduling context, workflow instance details, and call stack depth to enhance execution monitoring and debugging capabilities.
* Add call stack visualization for activity executions
Introduced components and models to display a call stack for activity executions in the Workflow Instance Viewer. This includes UI elements for call stack rendering, error handling, and data integration with activity execution records.
