Remove unused imports across 86 files in src/, web_interface/, test/, and scripts/ using autoflake. No logic changes — only dead import statements and unused names in from-imports are removed. Also remove bare exception aliases where the variable is never referenced in the handler body: - src/cache/disk_cache.py: except (IOError, OSError, PermissionError) as e - src/cache_manager.py: except (OSError, IOError, PermissionError) as perm_error - src/plugin_system/resource_monitor.py: except Exception as e - web_interface/app.py: except Exception as read_err 86 files changed, 205 lines removed, 18 pre-existing test failures unchanged.
