v0.6.1 — fix UTF-8 BOM in settings.json parsing

cce v0.6.1 — 修复带 BOM 的 settings.json 解析 / fix BOM-prefixed settings.json parsing

带 UTF-8 BOM 的 ~/.claude/settings.json 会被 cce 误判为无法解析、当成空配置处理（Unexpected token ''）。Windows 上不少编辑器写文件会自动加 BOM。Claude 本体会先剥掉 BOM 再解析，cce 现在行为对齐。

A ~/.claude/settings.json carrying a UTF-8 BOM was wrongly reported as unparseable and treated as empty (Unexpected token ''). Many editors on Windows add a BOM when saving. Claude itself strips the BOM before parsing — cce now matches that behavior.

修复 / Fixes

• BOM 容错 / BOM tolerance：新增 parseJson()，解析前剥掉开头的 U+FEFF。用户可编辑文件的读取（settings.json 的 env 读取、cce 主配置加载与语言探测）统一走它。非法 JSON 仍照常报错。/ New parseJson() strips a leading U+FEFF before parsing; all user-editable file reads (settings.json env, cce config load + language peek) route through it. Genuinely invalid JSON still errors as before.
