Support sample table data in DBML

[hdnax]

Summary

Add support for sample table data in DBML.

Doc: https://github.com/holistics/dbml/blob/78d79441758adc973376a18531b8d0b3807f9208/dbml-homepage/docs/docs.md
TDD: https://www.notion.so/holistics/TDD-80-Sample-Table-Data-2e6f89dc7e498073ac17c09a842aa64b

Support CommaExpressionNode in parser

• Added CommaExpressionNode to AST for comma-separated value lists
• Added lexer support for scientific notation (e.g., 1.23e5, -4.56e-3)

Support sample table data in DBML

Table Users {
  id string [pk]
  name string
  age int

  Records { // implicit columns
    "id1", "Alice", 18
    "id2", "Bob", 19
  }

  Records (id, name) { // explicit columns
    "id3", "Charlie"
  }
}

Records Users(id, name) { // always explicit
  "id4", "David"
}

• Implicit/explicit column lists
• Full type validation and constraint checking (PK, FK, unique, not null)
• Support for strings, numbers, booleans, dates, enums, null, and SQL expressions
• Validation warnings instead of errors for constraint violations

Handle INSERT statements in importers and exporters

Exporters: Convert Records to INSERT statements for all SQL dialects (MySQL, PostgreSQL, Oracle, MSSQL, Snowflake) with automatic FK constraint handling

Importers: Parse INSERT statements from SQL and convert to DBML Records, including Snowflake support

Add diagnostics provider for reusable logic related to errors and warnings

• New DBMLDiagnosticsProvider class with provideDiagnostics(), provideErrors(), provideWarnings() methods

Others

• Hardcode Report<T, E> to Report

  • E is now always CompileError, also CompileWarning is supported
  • Simplified API with getErrors() and getWarnings() methods

• Expose reusable SQL type checking and value extraction functions

  • Type checkers: isSqlNumericType(), isSqlStringType(), isSqlDateTimeType(), isSqlBooleanType()
  • Value extractors: tryExtractBoolean(), tryExtractInteger(), tryExtractFloat(), tryExtractString(), tryExtractDate(), tryExtractDateTime(), tryExtractTime()
  • Utilities: normalizeRecordValue(), addDoubleQuoteIfNeeded()
