fix(v2): strip CLAUDE* env vars at Rust level in SidecarManager

Browse source 
Add env_clear() + envs(clean_env) to Command in SidecarManager to
filter all CLAUDE-prefixed environment variables before spawning the
sidecar process. This provides primary defense against SDK nesting
detection when BTerminal is launched from a Claude Code terminal.
The JS-side stripping via SDK env option is retained as defense-in-depth.
