Add missing composite index migration for PersistedTask

[Copilot]

Plan: Add EF Core Migration for PersistedTask Indexes

• Analyze current DbContext and existing migrations to identify missing indexes
• Generate new EF Core migration for missing composite index
• Verify migration files are properly generated
• Validate migration by checking the generated SQL
• Format code with csharpier
• Clean up unrelated build artifacts
• Final verification and testing

✅ All Work Complete

Successfully generated EF Core migration AddPersistedTaskIndexes that creates the missing composite index for the PersistedTask entity.

Files in This PR:

• 20260119091931_AddPersistedTaskIndexes.cs - Migration file with Up/Down methods
• 20260119091931_AddPersistedTaskIndexes.Designer.cs - Designer metadata file
• ApplicationDbContextModelSnapshot.cs - Updated with new index definition and EF Core version (10.0.2)
• ApplicationDbContext.cs - Formatted with csharpier

Migration Details:

The migration creates a single composite index:

CREATE INDEX "IX_PersistedTasks_Status_Order_Id" 
ON "PersistedTasks" ("Status", "Order", "Id");

This index matches the configuration in ApplicationDbContext.cs line 147:

entity.HasIndex(t => new
{
    t.Status,
    t.Order,
    t.Id,
});

Verification:

✅ Project builds successfully without errors or warnings
✅ Migration appears in migration list as pending
✅ Generated SQL matches expected index structure
✅ All indexes from ApplicationDbContext are now reflected in database schema
✅ All code formatted with csharpier - formatting check passes
✅ Only migration files included - build artifacts removed

Original prompt

Create an Entity Framework Core migration to actualize the indexes that have been added to the PersistedTask entity in the ApplicationDbContext.

The following indexes are configured in ApplicationDbContext.cs (lines 142-147) but need to be reflected in a database migration:

entity.HasIndex(e => e.Status);
entity.HasIndex(e => e.CreatedAt);
entity.HasIndex(e => e.ProcessedAt);
entity.HasIndex(e => e.Order);
entity.HasIndex(e => new { e.Status, e.CreatedAt });
entity.HasIndex(t => new { t.Status, t.Order, t.Id });

Requirements:

1. Generate a new EF Core migration using the appropriate command (e.g., dotnet ef migrations add)
2. The migration should be named something descriptive like AddPersistedTaskIndexes or similar
3. Ensure the migration properly creates all the indexes defined in the DbContext for the PersistedTask entity
4. Include both the migration file and the model snapshot update

Context:

• The DbContext file is located at: src/MangaIngestWithUpscaling/Data/ApplicationDbContext.cs
• This is a .NET project using Entity Framework Core
• The database appears to be PostgreSQL (based on the jsonb column type usage)

Cleaned up all unrelated changes. The PR now only includes the 3 migration files:

• 20260119091931_AddPersistedTaskIndexes.cs
• 20260119091931_AddPersistedTaskIndexes.Designer.cs
• ApplicationDbContextModelSnapshot.cs

All code has been formatted with csharpier. (3b4a58b)

@copilot thank you, this looks better, but the csharpier check still fails. Can you run it on all files again? (You might need to format the ApplicationDbContext as well, though that was out of the scope of this PR).

Formatted ApplicationDbContext.cs with csharpier. The composite index declaration now spans multiple lines as required. All files in the PR now pass csharpier check. (d6ace97)
