- Detect v2 archives by checking EOF block for --AI1WM. prefix
- Parse path (4088 bytes) and CRC (8 bytes) fields conditionally
- Verify archive-level CRC via zlib on validation
- Verify per-file CRC after extraction, log on mismatch
- Replace dead eof member with isV2 flag
- Fix overlapping buttons by adding spacing to button layout

- Update v2 EOF detection to match new format: a255(null) + a14(size) + a4100(null) + a8(crc) - Fix CRC extraction offset from 8 to 4369 - Stop extraction on archive CRC mismatch instead of just warning - Show user-friendly error with clickable KB link on CRC failure - Use specific error message when available instead of generic wrapper
