Port from earendil-works/pi#8337 (UTF-8 BOM normalization in text inputs): sibling sites the merged #81967 BOM sweep missed. json.loads hard-fails on a leading U+FEFF and every one of these loaders swallows the exception and silently falls back to defaults — a user who edited mem0.json, honcho.json, hindsight/config.json, or supermemory.json in Notepad lost their whole config with no error, and Qwen CLI OAuth creds saved with a BOM raised qwen_auth_read_failed. - plugins/memory/{honcho,mem0,hindsight,supermemory}: 13 read sites -> utf-8-sig - hermes_cli/auth.py: _read_qwen_cli_tokens -> utf-8-sig - tests: BOM regression tests per loader (sabotage-proven) + plain-UTF-8 guard
