Add format, compression, and frame count to metadata extraction

[Copilot]

• Add new metadata fields to ImageMetadata interface (format, compression, frameCount, bitDepth, colorType)
• Update PNG extractMetadata to include format, compression (deflate), bit depth, color type
• Update APNG extractMetadata to include format, compression (deflate), frame count
• Update JPEG extractMetadata to include format, compression (baseline DCT)
• Update WebP extractMetadata to include format, compression (VP8/VP8L), frame count
• Update GIF extractMetadata to include format, compression (LZW), frame count
• Update TIFF extractMetadata to include format, compression type, frame count
• Update BMP extractMetadata to include format, compression type
• Update other formats (ICO, DNG, PAM, PCX, PPM, ASCII) to include format metadata
• Add tests for new metadata fields
• Run precommit checks and fix any issues
• Address code review feedback
• Fix test compatibility for Bun and Node by using @cross/test

Original prompt

Add number of frames (for multi frame images), file format, compression algorithm, etc to metadata extraction (where possible without actually decoding).

@copilot Bun ando Node tests are failing, Use @cross/test instead of Deno.test in tests

Fixed in 60ebcd3. Replaced all Deno.test calls with test from @cross/test for cross-runtime compatibility with Bun and Node.
