Add edge case test coverage for query and validation schemas

[Copilot]

Week 4: Testing & Documentation - Comprehensive Test Coverage ✅

Summary

Successfully added comprehensive edge case tests to achieve and maintain 100% test coverage for both query.zod.ts and validation.zod.ts. Also fixed CI build issues in the documentation site.

Completed Tasks

• Review existing test coverage for query.zod.ts (Currently at 100%)
• Review existing test coverage for validation.zod.ts (Currently at 100%)
• Add edge case tests for query.zod.ts (null handling, type coercion, boundary conditions)
• Add edge case tests for validation.zod.ts (null handling, type coercion, boundary conditions)
• Verify all tests pass (819 tests passing)
• Verify coverage remains at 90%+ (Both files at 100%)
• Code review completed (No issues found)
• Security scan completed (No vulnerabilities found)
• Fix CI build failures (Documentation build errors resolved)

Test Coverage Achieved

• query.zod.ts: 100% (Statements/Branch/Functions/Lines)
• validation.zod.ts: 100% (Statements/Branch/Functions/Lines)
• Total Tests: 819 passed (26 test files)

Edge Cases Added

query.zod.ts (23 new tests):

• Null/undefined values in filter expressions
• Empty arrays for fields, aggregations, joins
• Type coercion (numbers, booleans, strings in filters)
• Optional field handling with undefined properties
• Boundary conditions (zero values, large pagination)
• Complex nested filters and having clauses
• Optional properties in window functions
• Default values verification
• Invalid input rejection tests

validation.zod.ts (30 new tests):

• Null/undefined with proper defaults
• Empty arrays/strings in validation fields
• All format types (email, url, phone, json)
• Complex state machine transitions (20+ states)
• Timeout edge cases (100ms to 60s)
• Debounce edge cases (0ms to 5s)
• Nested conditional validations
• Boundary conditions (long names, many fields)
• Comprehensive params handling

CI Build Fixes

• Fixed syntax error in content/docs/index.cn.mdx (Chinese quotation marks)
• Replaced fumadocs-ui Callout components with Markdown blockquotes to resolve Turbopack module resolution issues
• All builds now passing (packages, docs, examples)

Quality Assurance

• ✅ All tests passing
• ✅ 100% code coverage
• ✅ No code review issues
• ✅ No security vulnerabilities
• ✅ No breaking changes
• ✅ CI build passing

@copilot fix ci build test

Fixed in 76a0b8b. The CI build was failing due to documentation build errors (unrelated to the test changes):

1. Syntax error in index.cn.mdx: Chinese quotation marks (") in MDX attributes were causing parsing errors
2. Turbopack module resolution issue: The fumadocs-ui/components/callout import couldn't be resolved during build

Resolution: Replaced Callout components with Markdown blockquotes and fixed the Chinese quotation marks. All builds now passing.
