Severity: High

When launching claude or codex:

c.Env = append(os.Environ(), "ANTHROPIC_BASE_URL="+base, ...)

os.Environ() passes all parent env vars to the child, including OCGO_API_KEY. Any subprocess run by claude/codex can read the API key from /proc/<pid>/environ or environment inspection.

File: cmd/ocgo/main.go:234-237, cmd/ocgo/main.go:276

Fix: Filter OCGO_API_KEY out of the environment before passing to children, or build a clean env without it.
