fix: wrapper scripts for all CLIs — env vars work immediately without source

Problem: `sudo bash install.sh` runs in child process, `export` inside it
never reaches the user's current shell. /etc/environment and /etc/profile.d/
only work for NEW sessions. So `codex`/`gemini`/`qwen` fail with
"Missing environment variable" right after install.

Solution: wrapper scripts that auto-source env file before exec'ing binary.
- codex: /usr/local/bin/codex (wrapper) -> /usr/local/bin/.codex-bin (real)
- gemini: /usr/local/bin/gemini (wrapper) -> node .../dist/index.js
- qwen: /usr/local/bin/qwen (wrapper) -> node .../dist/index.js

Works immediately in ANY shell, no manual `source` needed.
