All uncommitted work from ESP32 GDB stub development session. Includes: - GDB stub (uos_gdbstub.c/.h/_entry.S) - Startup vector table rewrite - ESP32 HAL integration files - Boot chain design docs - AGENTS.md absolute rules (commit before refactor, no unauthorized changes) - All prior deepseek session work This commit prevents further data loss. No claims of correctness.
