This commit addresses 6 identified bugs found through systematic repository analysis:

HIGH SEVERITY:
- fix(schema): ObjectSchema.strip() now properly overrides passthrough/strict modes
  * Previously strip() was a no-op, causing unexpected behavior when chained
  * Added 3 new tests to verify strip() behavior and mode overriding
  * Fixes src/schema.ts:528-532

MEDIUM SEVERITY:
- fix(stringifier): use keyEncoder instead of encoder for Date field keys
  * Ensures consistent encoding behavior for all object keys
  * Fixes src/stringifier.ts:195

- fix(eslint): pin ESLint to v8.57.0 for .eslintrc.js compatibility
  * ESLint 9.x requires new flat config format
  * Ensures npm run lint works correctly
  * Fixes package.json devDependencies

LOW SEVERITY:
- refactor(stringifier): remove unreachable null check code
  * Dead code already handled earlier in the function
  * Improves code coverage from 99.09% to 99.33%
  * Fixes src/stringifier.ts:190-192

- refactor(parser): remove useless comma string operation
  * val.split(',').join(',') is a no-op
  * Comma handling done correctly elsewhere in codebase
  * Fixes src/parser.ts:118-120

- refactor(security): remove redundant prototype pollution check
  * Object.getOwnPropertyNames() already covers enumerable properties
  * Minor performance improvement
  * Fixes src/security.ts:162-172

TESTING:
- All 495 tests pass (3 new tests added for strip() fix)
- Code coverage increased: 99.09% → 99.33% statements
- Zero breaking changes - all fixes are backward compatible

DOCUMENTATION:
- Added BUG_ANALYSIS_REPORT.md with detailed bug analysis
- Added BUG_FIX_SUMMARY.md with fix verification results

Summary of Changes

Hello @ersinkoc, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request delivers a comprehensive set of bug fixes resulting from a thorough repository analysis. It addresses six identified issues, including a critical functional bug in the strip() method, an ESLint configuration incompatibility, and several code quality improvements. The changes enhance the project's reliability, maintainability, and development workflow, all while maintaining a 100% test pass rate and improving code coverage, with no breaking changes introduced.

Highlights

  • Critical Bug Fix: Resolved a high-priority bug where the ObjectSchema.strip() method was non-functional. It now correctly disables passthrough() and strict() modes, ensuring it behaves as expected to remove unknown properties.
  • ESLint Compatibility Restored: Fixed the ESLint configuration issue by pinning the dependency to v8.57.0. This resolves the incompatibility with ESLint 9.x and restores the functionality of npm run lint.
  • Encoder Consistency in Stringifier: Corrected an issue in the stringifier where the wrong encoder was used for Date field keys. It now consistently uses keyEncoder instead of encoder, ensuring proper encoding behavior with custom encoder functions.
  • Code Cleanup and Optimization: Removed several instances of dead or redundant code, including a useless string operation in the parser, unreachable null/undefined checks in the stringifier, and redundant prototype pollution checks in the security module. These changes improve code clarity and offer minor performance gains.
  • Improved Test Coverage: Increased overall test coverage from 99.09% to 99.33% (statements) and added 3 new comprehensive tests specifically for the ObjectSchema.strip() functionality, ensuring its correctness.
  • Comprehensive Documentation Added: Introduced extensive documentation including a detailed bug analysis report, a summary of fixes, a code quality roadmap, a project health report, and various release-related drafts. This provides a thorough overview of the project's status and future direction.

Code Review

This pull request introduces a comprehensive set of bug fixes and a large amount of generated documentation detailing the analysis and resolution process. The code changes are solid, well-reasoned, and include corresponding tests, which is excellent. My review focuses on some inconsistencies found within the newly generated documentation files, particularly concerning the details of the ESLint version fix. Addressing these will ensure the reports are accurate and consistent with the code changes.
