Preserves all CLI flags when reloading, not just --dangerously-skip-permissions.
Before: Reload resumed with claude --resume <id> — losing model, effort, permissions, custom dirs, and all other flags.
After: Reads the running process args, strips resume/continue, keeps everything else:
Original: claude --dangerously-skip-permissions --model opus --effort max
Resume: claude --dangerously-skip-permissions --model opus --effort max --resume <id>
Flags preserved: --model, --effort, --add-dir, --allowedTools, --disallowedTools, --append-system-prompt, --bare, --mcp-config, --dangerously-skip-permissions, and any others.
