- Position as clear alternative to manual pagination implementations
- Framework-agnostic design with modern PHP 8.2+ features

* Apply fixes from StyleCI (#9)

Co-authored-by: Igor Pinchuk <somework@users.noreply.github.com>

* fix: enable Xdebug for code coverage in CI

- Enable Xdebug in composer-install action (coverage: xdebug)
- Make coverage artifact upload conditional on success
- Ensure coverage reports are properly generated in CI pipeline

Resolves PHPUnit warning: 'No code coverage driver available'

* fix: address CodeRabbit review comments

- README: Fix streaming example to use strict null check instead of truthy check
- OffsetResult: Remove unused InvalidPaginationResultException import
- OffsetResult: Remove incorrect @throws annotation from fetchAll() method
- SourceInterface: Update @param types from positive-int to int to match actual contract
- PropertyBasedTest: Fix callback signatures to accept required (int $page, int $pageSize) parameters
- Style: Auto-fix code formatting with CS fixer

All tests pass (96/96) and quality checks pass.

* polish: address final CodeRabbit review suggestions

Code Quality & Clarity:
- Simplify ArraySource ternary to if-statement for better readability
- Add safety guard to prevent infinite loops in IntegrationTest
- Clarify nowCount parameter behavior with detailed comments
- Use yield from [] consistently for empty generators

Test Improvements:
- Rename misleading testError() to testZeroLimitReturnsEmptyResult()
- Add specific exception message assertions for better test precision
- Verify expected fetched data values instead of just counts

Documentation & Safety:
- Update UPGRADE.md to clarify removed types (interface vs class)
- Add consumption warning to OffsetResult::generator() method
- Use array_key_exists for more precise parameter handling

All tests pass (96/96, 488 assertions) and quality checks clean.

* perf: make CI coverage configurable for optimal performance

- Add optional coverage input to composer-install action (default: none)
- Enable xdebug only for tests job, disable for quality job
- Reduces CI overhead by avoiding unnecessary coverage instrumentation
- Maintains coverage generation where needed while optimizing performance

Addresses CodeRabbit suggestion for configurable coverage.

* fix: address final CodeRabbit suggestions for code quality

- README: Convert bold text to proper heading to avoid markdownlint MD036
- Tests: Parameter names already prefixed with underscores (previously fixed)
- Quality: All static analysis and linting checks pass cleanly

Completes the comprehensive CodeRabbit review response.

* test: add comprehensive tests for OffsetAdapter::fromCallback method

- Add testFromCallbackCreatesAdapterWithCallbackSource() to verify fromCallback works
- Add testFromCallbackWithEmptyData() for edge case testing
- Tests cover pagination behavior and callback invocation
- Improves method coverage from 55.56% to higher percentage

Resolves coverage gap for the fromCallback static factory method.

* test: improve OffsetAdapter test coverage

- Add comprehensive fromCallback method tests
- Add edge case tests for empty generators
- Add comprehensive method execution test
- Improve method coverage from 66.67% to 77.78% (7/9 methods)
- Improve line coverage from 92.86% to 95.24% (40/42 lines)

Remaining 2 uncovered lines are in AlreadyGetNeededCountException catch block,
which is a pagination optimization exception that may be difficult to trigger reliably.

* test: achieve near-perfect OffsetAdapter coverage

- Improve method coverage from 77.78% to 88.89% (8/9 methods)
- Improve line coverage from 95.24% to 97.62% (41/42 lines)
- Add testLimitReachedInGeneratorProcessing() to cover break condition in createLimitedGenerator
- Add testPaginationWithExtremeParameters() for edge case handling
- Successfully covered limit enforcement logic (line 204)

Remaining 1 uncovered line (line 138) is safety check for invalid pagination parameters,
which is an edge case unlikely to occur in normal operation with the pagination library.

* test: add coverage for PaginationException base class

- Add testPaginationExceptionBaseClass() to verify inheritance and interface implementation
- PaginationException is an empty base class, so 0% coverage is expected (no executable lines)
- Confirms proper inheritance: RuntimeException -> PaginationException -> PaginationExceptionInterface

Functional classes maintain excellent coverage:
- OffsetAdapter: 88.89% methods, 97.62% lines
- OffsetResult: 100% methods, 100% lines
- SourceCallbackAdapter: 100% methods, 100% lines
- Exception classes: 100% coverage each

* feat: complete package transformation to production-ready solution

Transformed offset-page from functional library to Packagist-ready, DX-first solution:
- Enhanced API with fromCallback() and fetchAll() convenience methods
- Enterprise exception architecture with comprehensive error handling
- Complete documentation overhaul (README, CONTRIBUTING, UPGRADE)
- Packagist optimization with SEO keywords and metadata
- 99.07% line coverage, 104 tests, enterprise-grade quality
- Removed unused PaginationException dead code

29 files changed, 1831 additions, 1356 deletions
104 tests passing, 509 assertions
Ready for production release!
