Added

• Initial release of asset_shrink.

• JPEG compression pipeline with native jpegoptim and pure-Dart lossless metadata stripping.
• PNG color-type header parser with $\ge 33$-byte corruption guard.
• Core invariant size gate: files are strictly overwritten only when candidate bytes are smaller than original bytes.
• Zero-history stateless execution: decisions are made purely from current image bytes.
• Automatic native tool detection with platform-specific installation hints.
• Per-file exception isolation ensuring corrupted files never abort the batch.
• CLI runner supporting --quality, --jpg-quality, --dry-run, --verbose, and custom path overrides.
