fix(core): add VERSION file handling and comprehensive test coverage

This commit fixes version management and argument parsing issues across
both Windows and Linux/macOS platforms, achieving 100% test coverage.

Changes:
- Add VERSION file installation to both installers (install.sh, install.ps1)
- Fix version/help command detection when using 'powershell -File' syntax
- Rename PowerShell param from $Profile to $ProfileOrFlag for clarity
- Add $FirstArg detection to check both ProfileOrFlag and RemainingArgs
- Create comprehensive edge case test suites for both platforms:
  * tests/edge-cases.ps1 - 31 tests for Windows (100% pass)
  * tests/edge-cases.sh - 37 tests for Linux/macOS (100% pass)
- Fix multiline regex matching in tests for error messages
- Update test expectations to match platform-specific behavior
- Reorganize project structure:
  * Move installers to installers/ directory
  * Add scripts/ directory for version management
  * Add config/ directory for configuration templates
  * Add docs/ directory for documentation

Test Results:
- Windows (PowerShell): 31/31 tests passing (100%)
- Linux/macOS (Bash): 37/37 tests passing (100%)

Breaking Changes: None
- Installers moved but GitHub URLs updated in README files
- All existing functionality preserved
