Compute CRC-32 checksums

Paste text to compute its CRC-32 (IEEE 802.3) checksum — the same non-cryptographic checksum used by ZIP entries, PNG chunks, gzip members, and Ethernet frames. The result is shown as 8-character lowercase hex (how crc32 CLIs print it) and as an unsigned 32-bit decimal (how PNG stores it), each independently copyable.
