- Search: string/wide/case-insensitive/Rabin-Karp/JSON searches now use _cmd_arg so patterns with spaces/special chars are safe.
- Flags: removed leftover manual _tmp_off = "" cleanups (now automatic).
- Debugger: added _tmp_addr() helper, removed manual _tmp_off cleanup.
- Esil: ESIL expressions use _cmd_arg; EsilCPU.registers() returns {} on failure; emulateInstr resolves symbol names to numeric
addresses because aesp doesn't accept symbols.
- Config: cleaned up old-style super() and % formatting; config set now uses key=value.
- File: minor __getattr__ cleanup.
- IOMap: setName uses _cmd_arg for arbitrary map names.
- R2Api / Function: af, afn, afn., p8, aoj, axtj now rely on automatic _tmp_off handling; removed duplicated open/files definitions.
