Implement src/engine/debuglog module that records a comprehensive snapshot of game state every tick into a 4 MB in-memory ring buffer. Activated by --debug-log command-line flag. Press F12 during gameplay to dump the ring buffer to a human-readable debug_log.txt file. The buffer also auto-flushes every 10 seconds as a safety net. Each tick snapshot captures: input state (held/pressed/released bitmasks), full player state (position, velocity, health, dash, aim, timers), camera position, physics globals, level name, and a variable-length list of all active entity positions/velocities/health. New files: - src/engine/debuglog.h — API and snapshot data structures - src/engine/debuglog.c — ring buffer, record, and dump logic Modified files: - include/config.h — DEBUGLOG_BUFFER_SIZE constant - src/engine/input.h/c — input_get_snapshot() to pack input bitmasks - src/engine/core.c — debuglog_record_tick() call after update - src/main.c — CLI flag, init/shutdown, F12 hotkey, set_level calls Closes #19
