#!/usr/bin/env bun

🔴 HIGH RISK

The hashbang #!/usr/bin/env bun restricts execution to environments where Bun is installed, contradicting the engines field in package.json that explicitly supports Node.js (>= 18.0.0). On systems with only Node.js, the affinescript command will fail to execute. Using node as the interpreter ensures compatibility with both Node and Bun.

#!/usr/bin/env bun
#!/usr/bin/env node

Make the executable launcher compatible with Node.js.

The bun hashbang prevents /usr/bin/env from starting packages/affinescript-cli/bin/affinescript.js on a Node-only installation, despite the package declaring Node.js >=18.0.0 support. Replace it with a runtime-selecting launcher and test Node-only and Bun-only installations.

In `@packages/affinescript-cli/bin/affinescript.js` at line 1, Update the
executable launcher at the top of affinescript.js to select an available runtime
instead of hard-coding Bun, while preserving direct execution under both Node.js
and Bun. Verify the launcher works in Node-only and Bun-only installations.

// else — all behaviour stays in mod.js.
