Add dab auto-config-simulate CLI command

[Copilot]

Why make this change?

Developers using autoentities needed a way to preview which database objects would be matched by their filter definitions before committing changes to the config.

What is this change?

New auto-config-simulate verb that connects to the MSSQL database, executes the autoentities pattern-match query for each filter definition, and outputs results.

New files:

• src/Cli/Commands/AutoConfigSimulateOptions.cs — defines the auto-config-simulate verb with optional --output/-o flag
• src/Cli.Tests/AutoConfigSimulateTests.cs — unit and integration tests for the simulate command

ConfigGenerator.cs additions:

• TrySimulateAutoentities — loads config (with env-var resolution), validates MSSQL + autoentities present, opens a SqlConnection, and runs MsSqlQueryBuilder.BuildGetAutoentitiesQuery() for each defined filter using explicit SqlParameter instances with SqlDbType.NVarChar
• WriteSimulationResultsToConsole — prints grouped output with match counts and aligned entity → schema.object lines
• WriteSimulationResultsToCsvFile — writes RFC 4180-compliant CSV (values are properly quoted/escaped)
• QuoteCsvValue — helper that wraps and escapes commas, quotes, and newlines in CSV fields

Program.cs: registers AutoConfigSimulateOptions in the parser.

How was this tested?

• Integration Tests — AutoConfigSimulateTests.cs covers: filter matching a known table with console output, filter matching a known table with CSV file output, and filter matching no tables (all marked [TestCategory("MsSql")], skip gracefully when MSSQL_SA_PASSWORD is not set).
• Unit Tests — AutoConfigSimulateTests.cs covers: no autoentities defined.

Sample Request(s)

Console output (default):

dab auto-config-simulate

AutoEntities Simulation Results

Filter: ProductTables

Products  -> dbo.Products
Inventory -> dbo.Inventory
Pricing   -> dbo.Pricing

Filter: AnotherFilter
Matches: 0

(no matches)

CSV file output:

dab auto-config-simulate --output results.csv

Just as a heads up, I was blocked by some firewall rules while working on your feedback. Expand below for details.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• http://api.nuget.org:443/DigiCertTrustedG4CodeSigningRSA4096SHA3842021CA1.crl
  • Triggering command: /usr/bin/dotnet dotnet build src/Cli.Tests/Cli.Tests.csproj --no-incremental -p:TreatWarningsAsErrors=false (http block)
• http://api.nuget.org:443/DigiCertTrustedG4RSA4096SHA256TimeStampingCA.crl
  • Triggering command: /usr/bin/dotnet dotnet build src/Cli.Tests/Cli.Tests.csproj --no-incremental -p:TreatWarningsAsErrors=false (http block)
• http://api.nuget.org:443/DigiCertTrustedG4TimeStampingRSA4096SHA2562025CA1.crl
  • Triggering command: /usr/bin/dotnet dotnet build src/Cli.Tests/Cli.Tests.csproj --no-incremental -p:TreatWarningsAsErrors=false (http block)

  • Triggering command: /usr/bin/dotnet dotnet build src/Cli.Tests/Cli.Tests.csproj --no-incremental -p:TreatWarningsAsErrors=false (http block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
