Fixes#326
## Summary
- source the user's bash or zsh rc before launching the bundled CLI from
Tauri
- use `-l -i -c` for zsh so shell-managed Node runtimes are available in
launcher-started sessions
- fixes the reproduced Linux launcher case where the app exits with `CLI
exited early: exit status: 127` while terminal launches work
## Validation
- reproduced the failure with the released Tauri `v0.14.0` Linux binary
- verified the patched binary succeeds under the same launcher-like
environment
- ran `cargo build` on the dev-based PR branch
