Add support for identifying games inside ZIP, 7z, and RAR archives using MiSTer-style paths (e.g., /path/to/archive.zip/folder/game.gba) and auto-detection when given just an archive path. New archive package: - archive.go: Core Archive interface and factory function - zip.go: ZIP implementation using stdlib archive/zip - sevenzip.go: 7z implementation using bodgit/sevenzip - rar.go: RAR implementation using nwaples/rardecode/v2 - path.go: MiSTer-style path parsing - detect.go: Game file detection by extension - errors.go: Error types (FormatError, FileNotFoundError, etc.) Features: - Explicit internal paths: /games/roms.zip/gba/game.gba - Auto-detect game file: /games/roms.zip (finds first game by extension) - Supports cartridge-based games only (GB, GBC, GBA, NES, SNES, N64, Genesis) - Disc-based games in archives return DiscNotSupportedError Dependencies added: - github.com/bodgit/sevenzip (BSD-3-Clause) - github.com/nwaples/rardecode/v2 (BSD-2-Clause)

Add comprehensive tests to improve patch coverage: - TestSevenZipAndRAR_Operations: Consolidated table-driven tests for 7z and RAR archive operations (List, Open, OpenReaderAt, case-insensitive matching) - TestDetectConsoleFromExtension: Full coverage for extension-based console detection including ambiguous extensions, .gz suffix handling, and edge cases - TestIdentifyFromArchive_*: Tests for archive identification including direct calls, disc console errors, unsupported consoles, and non-existent files - TestDetectConsoleFromCue_*: Tests for CUE sheet console detection including Saturn and SegaCD magic headers, empty CUE files, and missing BIN files - TestByteReaderAt edge cases: Fixed errorlint issues using errors.Is() Coverage improvements: - DetectConsoleFromExtension: 44.4% -> 100% - detectConsoleFromCue: 0% -> 69.6% - IdentifyFromArchive: 0% -> 88.2% - archive/sevenzip.go: 0% -> covered - archive/rar.go: 0% -> covered
