1. Fix theme store download resumable transfer causing file corruption issue — When downloading via proxy (gh-proxy/gitee), only resume appending when server truly returns 206, and start over when server returns 200, preventing "half+complete" concatenation damage. .fpt; progress calculation synchronized corrected, progress smoothly increments instead of freezing when size unknown.
2. Fix theme store download error showing null and preview blocking installation* — Real reasons for download failure (HTTP status code, exception type) are no longer swallowed, empty URL and no message exceptions give clear prompts; preview download failure is downgraded to non-fatal, theme can still be installed normally.
3. Fix large module installation log causing TransactionTooLargeException crash — Merged upstream commit (cherry-pick), log displays status truncated at 100K characters, adapted to this fork's throttling/dual-buffer architecture.
4. Complete multi-language characters for cropping wallpaper feature — Added 5 strings introduced by free cropping feature for 17 language files.
5. Add custom wallpaper free cropping feature (#164) — Main commit merged, new capability added to this repository
