Native logging that's more reliable#68

Conversation
Replace shell redirect logging with native file logging for better crash debugging. C binaries now use LOG_FILE env var to write logs directly, with optional LOG_SYNC=1 for fsync after each write.
Adds LOG_debug calls through the initialization of minui, minarch, and shui to help diagnose boot crashes. Also fixes shui to log to its own file (shui.log) instead of inheriting minui.log.

Pull request overview
This pull request adds comprehensive native logging infrastructure to help track down crashes in C binaries across various platforms. The changes introduce a new global logging API that uses environment variables (LOG_FILE and LOG_SYNC) to configure file-based logging with optional crash-safe synchronization.
Key changes:
- Implements
log_open()andlog_close()API for global logging initialization with environment variable support - Adds signal handlers (SIGTERM/SIGINT) to keymon daemons for clean shutdown and proper log flushing
- Updates platform init scripts to set
LOG_FILEenvironment variable for keymon - Adds extensive debug logging throughout minarch and shui for initialization tracking
