🐟 Sameko Dev C++ v1.2.0 Release ⚓

🌟 Version 1.2.0 is a landmark release! Featuring an integrated source-level C++ debugger (GDB), full cross-platform Linux support, xterm.js realtime output engine, SSOT theme customizer, local font performance boost, and tons of bug fixes.

🐛 1. Integrated C++ Debugger (GDB)

The app now features a real source-level debugger built on the bundled MinGW GDB (Machine Interface) — debug -g builds directly inside Sameko without leaving the editor!

• Breakpoints: Click left gutter to toggle red breakpoints. Alt+Click sets conditional breakpoints (e.g. i == n - 1); Ctrl+Click enables/disables breakpoints without deleting them.
• Interactive Debug Panel: Smart Run ▶ / Continue / Pause / Step Over (F10) / Step Into (F11) / Step Out (Shift+F11) / Stop (Shift+F5) toolbar. Step Into automatically skips std:: template internals!
• Variables & Watch Trees: Locals & watch expressions with full STL pretty-printing (vector, map, string expand dynamically). Changed values are highlighted in real-time. Double-click values to toggle Hex/Dec.
• Auto Dry Run & Step History: Walk programs automatically at custom speeds, or step backwards through pause history.
• Call Stack & Hover Evaluate: View stack frames, right-click to "Run to Cursor", and hover variables while paused to inspect values.

🐧 2. Full Cross-Platform Linux Support

Sameko is now officially available on Linux!

• Package Formats: Ships ready-to-run AppImage, .deb, and .tar.gz packages alongside Windows builds.
• Automatic Toolchain Detection: Automatically detects system-installed g++ and gdb without manual path configuration.
• Cross-Platform Architecture: Seamless POSIX process control, terminal management, file watching, and desktop integration.

⚡ 3. Engine, Performance & UI Upgrades

• Realtime Output Engine (xterm.js): Canvas-based xterm.js integration paired with a C++ std::cout/printf unbuffering shim (sameko_unbuffer.cpp) for instant line-by-line output in competitive programming.
• ~16% Faster Startup: Bundled local fonts (Fredoka, Nunito, JetBrains Mono) eliminating Google Fonts CDN roundtrips, paired with deferred Monaco editor loading.
• SSOT Theme Architecture: Single Source of Truth theme tokens (ThemeTokens), dark backdrop customizer popup, and unified color palette.
• Bundled GCC 16.1.0 & C++26: Updated WinLibs GCC 16.1.0 MinGW toolchain with official C++26 standard support.
