Enable strict validation by default in defineStack()

[Copilot]

Field name validation (snake_case requirement) existed in schema but was never enforced. defineStack() defaulted to strict: false, returning config as-is without running Zod validation.

Changes

Breaking Change: defineStack() now validates by default

• Changed DefineStackOptions.strict default: false → true
• Validation logic: const strict = options?.strict !== false
• Opt-out available via explicit strict: false

Validation enforcement

• Field names must match /^[a-z_][a-z0-9_]*$/ (snake_case)
• Object names, field types, and cross-references validated
• Clear error messages: "Field names must be lowercase snake_case"

Migration

// Now rejects invalid field names by default
defineStack({
  manifest: {...},
  objects: [{
    name: 'task',
    fields: {
      firstName: { type: 'text' }  // ❌ Error: must be snake_case
    }
  }]
});

// Fix: Use snake_case
fields: {
  first_name: { type: 'text' }  // ✅
}

// Or temporarily bypass (not recommended)
defineStack(config, { strict: false });

Files Modified

• stack.zod.ts: Default strict=true, updated logic
• stack.test.ts: Updated tests, added 4 validation tests
• field-name-validation.test.ts: New direct FieldSchema tests
• .changeset/strict-validation-by-default.md: Breaking change documentation

Original prompt

按规则，字段名必须是 snake_case，这里的代码是怎么 test 通过的？为什么启动没有报错？

Pull request overview

This PR enforces field name validation by changing defineStack() to validate by default. Previously, field names were required to be snake_case per the schema specification, but this validation was never enforced because defineStack() defaulted to strict: false and returned configurations as-is without running Zod validation.

Changes:

• Changed DefineStackOptions.strict default from false to true to enable validation by default
• Updated validation logic from if (!options?.strict) to const strict = options?.strict !== false; if (!strict)
• Updated tests to reflect new default behavior and added comprehensive field name validation tests
• Created changeset documenting this breaking change with migration guide
