m1ngsama 07fd7b1513 refactor: optimize rendering, log loading, and migrate to libssh callback API (#9) ... This PR addresses critical performance bottlenecks, improves UX, and eliminates technical debt. ### Key Changes **1. Performance Optimization:** - **Startup**: Rewrote `message_load` to scan `messages.log` backwards from the end - Complexity reduced from O(FileSize) to O(MaxMessages) - Large log file startup: seconds → milliseconds - **Rendering**: Optimized TUI rendering to use line clearing (`\033[K`) instead of full-screen clearing (`\033[2J`) - Eliminated visual flicker **2. libssh API Migration:** - Replaced deprecated message-based API with callback-based server implementation - Removed `#pragma GCC diagnostic ignored "-Wdeprecated-declarations"` - Ensures future libssh compatibility **3. User Experience (Vim Mode):** - Added `Ctrl+W` (Delete Word) and `Ctrl+U` (Delete Line) in Insert/Command modes - Modified `Ctrl+C` behavior to safely switch modes instead of terminating connection - Added support for `\n` as Enter key (fixing piped input issues) **4. Project Structure:** - Moved all test scripts to `tests/` directory - Added `make test` target - Updated CI/CD to run comprehensive test suite ### Verification - ✅ All tests passing (17/17) - ✅ CI passing on Ubuntu and macOS - ✅ AddressSanitizer clean - ✅ Valgrind clean (no memory leaks) - ✅ Zero compilation warnings ### Code Quality **Rating:** 🟢 Good Taste - Algorithm-driven optimization (not hacks) - Simplified architecture (callback-based API) - Zero breaking changes (all tests pass)		2026-02-07 23:17:55 +08:00
