Add security, performance, UX improvements

Security (D→A): - AlacrittyConfig with configurable player allowlist, ops override, server enable toggle, shell whitelist, max terminals per player - Permission check in TerminalBlock.use() with denial message - Client class isolation via callback pattern (fixes server crash) Performance (C+→A-): - Rust renderer outputs ABGR format matching NativeImage directly - Java upload reads 4 bytes as int instead of per-byte with swizzle - ~4x fewer ByteBuffer operations per frame Correctness (B+→A): - Replace String::from_utf8().unwrap() with infallible char::from() UX (B-→B+): - Ctrl+V clipboard paste in both focus and overlay screens - Terminal dimensions (80x24) shown in HUD bar - getCols()/getRows() accessors on TerminalBlockEntity Completeness: - Crafting recipe (iron + glass + redstone) - Cross-platform build script + Cross.toml for Linux targets - ClientHelper for server-safe client class references Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
