chore: bump version to 2.0.2

- Replace static test fixture files with dynamic test generation
- Implement comprehensive test suite with unit, integration, and golden master tests
- Add vim API mocking for standalone Lua test execution
- Fix pre-commit hook interference by eliminating external fixture files
- Add StyLua formatting for consistent Lua code style
- Enhance ShellSpec formatting with improved HEREDOC and comment handling
- Update documentation with new test architecture details

This resolves issues where pre-commit hooks (shfmt, end-of-file-fixer) were
modifying test fixture files and breaking golden master tests. The new dynamic
approach generates test data programmatically, making tests immune to formatting
tools while maintaining comprehensive coverage.

+# Development Commands
+
+## Key Make Targets
+
+- `make help` - Show all available targets with descriptions
+- `make check` - Quick health check (tools and version consistency)
+- `make test` - Run complete test suite
+- `make lint` - Run all linters
+- `make format` - Format all code (auto-fix where possible)
+- `make ci` - Full CI pipeline (check, test, lint)
+- `make clean` - Remove temporary files
+- `make dev-setup` - Set up development environment
+
+## Testing
+
+- `make test-unit` - Lua unit tests only
+- `make test-integration` - Integration tests
+- `make test-golden` - Golden master tests
+- `make test-bin` - Standalone formatter tests
+- Test runner: `./tests/run_tests.sh`
+
+## Linting
+
+- Uses pre-commit hooks
+- ShellCheck for shell scripts
+- StyLua for Lua formatting
+- markdownlint for Markdown
+- yamllint for YAML files
+- shfmt for shell script formatting
+
+## Version Management
+
+- Three files must stay in sync:
+  - `lua/shellspec/init.lua` (M._VERSION)
+  - `plugin/shellspec.vim` (g:shellspec_version)
+  - `bin/shellspec-format` (version string)
+- `make version-check` verifies consistency

+# Release Process
+
+## Command
+
+Always use `make release` for releases, not manual version bumping.
+
+## Available Release Commands
+
+- `make release` - Interactive release with menu (patch/minor/major)
+- `make release-patch` - Bump patch version (X.Y.Z → X.Y.Z+1)
+- `make release-minor` - Bump minor version (X.Y.Z → X.Y+1.0)
+- `make release-major` - Bump major version (X.Y.Z → X+1.0.0)
+
+## What make release does
+
+1. Checks git status is clean
+2. Verifies version consistency across files
+3. Runs complete test suite
+4. Runs all linters
+5. Calculates and prompts for new version
+6. Updates versions in all files:
+   - `lua/shellspec/init.lua` - M._VERSION
+   - `plugin/shellspec.vim` - g:shellspec_version
+   - `bin/shellspec-format` - version string
+7. Creates git commit with version bump
+8. Creates git tag (with v prefix, e.g., v2.0.3)
+9. Provides next steps for pushing
+
+## Manual Process (DO NOT USE)
+
+The old manual process was error-prone and didn't update all version files consistently.

+## Testing
+
+This plugin includes comprehensive tests to ensure formatting quality and reliability.
+
+### Running Tests
+
+```bash
+# Run all test suites
+./tests/run_tests.sh
+
+# Run individual test suites
+lua tests/format_spec.lua          # Unit tests
+./tests/integration_test.sh        # Integration tests  
+./tests/golden_master_test.sh      # Golden master tests
+```
+
+### Test Suites
+
+- **Unit Tests** (`tests/format_spec.lua`): Test core formatting functions with Lua - includes vim API mocking for standalone execution
+- **Integration Tests** (`tests/integration_test.sh`): Test plugin loading, command registration, and end-to-end functionality in Neovim
+- **Golden Master Tests** (`tests/golden_master_test.sh`): Compare actual formatting output against expected results using dynamic test generation
+
+### Test Architecture
+
+The test suite uses **dynamic test generation** to avoid pre-commit hook interference:
+
+- **No external fixture files**: Test data is defined programmatically within the test scripts
+- **Pre-commit safe**: No `.spec.sh` fixture files that can be modified by formatters
+- **Maintainable**: Test cases are co-located with test logic for easy updates
+- **Comprehensive coverage**: Tests basic indentation, comment handling, HEREDOC preservation, and nested contexts
+
+### Test Development
+
+When adding features or fixing bugs:
+
+1. Add unit tests for new formatting logic in `tests/format_spec.lua`
+2. Add integration tests for new commands/features in `tests/integration_test.sh`
+3. Add golden master test cases in the `TEST_CASES` array in `tests/golden_master_test.sh`
+4. Run `./tests/run_tests.sh` to verify all tests pass
+
+Example of adding a golden master test case:
+
+```bash
+"test_name|input_content|expected_content"
+```
