Implements bd-au0.4: Standardize priority flag parsing across all commands.
Changes:
- Use registerPriorityFlag() for main priority flag (was IntP)
- Change priority-min/max from Int to String flags
- Add validation import and use ValidatePriority() for all priority parsing
- Update both direct mode and daemon RPC code paths
Now supports both formats consistently:
- Numeric: --priority 0, --priority-min 1, --priority-max 2
- P-format: --priority P0, --priority-min P1, --priority-max P2
