When TruffleHog times out in pre-receive hooks, it fails to output
diagnostic logs.
Changes:
- Ensure log output is flushed before process termination in all exit paths:
* Defer log sync in run() function for normal exits
* Sync logs in signal handler before os.Exit(0)
* Sync logs before os.Exit(183) when results are found
* Sync logs in logFatalFunc before os.Exit() calls
- Use exec.CommandContext instead of exec.Command for git log/diff
to ensure processes are killed when context is cancelled
- Add WaitDelay to git commands to provide grace period for cleanup
This ensures diagnostic output is captured when git operations block in
pre-receive hook environments and logs are visible when process is killed.
