feat: performance, integrations, advanced features (#2)
* feat: performance, integrations, advanced features * chore: fix linting problems * chore: suppressions and linting * chore(lint): pre-commit linting, fixes * feat: comprehensive input validation, security hardening, and regression testing - Add extensive input validation throughout codebase with proper error handling - Implement comprehensive security hardening with ReDoS protection and bounds checking - Add 3 new regression test suites covering critical bugs, security, and validation scenarios - Enhance rate limiting with memory management and configurable cleanup intervals - Update configuration security settings and improve Laravel integration - Fix TODO.md timestamps to reflect actual development timeline - Strengthen static analysis configuration and improve code quality standards * feat: configure static analysis tools and enhance development workflow - Complete configuration of Psalm, PHPStan, and Rector for harmonious static analysis. - Fix invalid configurations and tool conflicts that prevented proper code quality analysis. - Add comprehensive safe analysis script with interactive workflow, backup/restore capabilities, and dry-run modes. Update documentation with linting policy requiring issue resolution over suppression. - Clean completed items from TODO to focus on actionable improvements. - All static analysis tools now work together seamlessly to provide code quality insights without breaking existing functionality. * fix(test): update Invalid regex pattern expectation * chore: phpstan, psalm fixes * chore: phpstan, psalm fixes, more tests * chore: tooling tweaks, cleanup * chore: tweaks to get the tests pass * fix(lint): rector config tweaks and successful run * feat: refactoring, more tests, fixes, cleanup * chore: deduplication, use constants * chore: psalm fixes * chore: ignore phpstan deliberate errors in tests * chore: improve codebase, deduplicate code * fix: lint * chore: deduplication, codebase simplification, sonarqube fixes * fix: resolve SonarQube reliability rating issues Fix useless object instantiation warnings in test files by assigning instantiated objects to variables. This resolves the SonarQube reliability rating issue (was C, now targeting A). Changes: - tests/Strategies/MaskingStrategiesTest.php: Fix 3 instances - tests/Strategies/FieldPathMaskingStrategyTest.php: Fix 1 instance The tests use expectException() to verify that constructors throw exceptions for invalid input. SonarQube flagged standalone `new` statements as useless. Fixed by assigning to variables with explicit unset() and fail() calls. All tests pass (623/623) and static analysis tools pass. * fix: resolve more SonarQube detected issues * fix: resolve psalm detected issues * fix: resolve more SonarQube detected issues * fix: resolve psalm detected issues * fix: duplications * fix: resolve SonarQube reliability rating issues * fix: resolve psalm and phpstan detected issues

* This test class serves as the definitive validation that all critical bugs

|

*
|
||||
* Critical Bug Fixes Validated:
|
||||
* 1. Type System Bug - Data type masking accepts all PHP types
|
||||
* 2. Memory Leak Fix - RateLimiter has cleanup mechanisms
|
||||
* 3. ReDoS Protection - Enhanced regex validation
|
||||
* 4. Error Sanitization - Sensitive info removed from error messages
|
||||
* 5. Laravel Integration - Fixed undefined variables and imports
