chore(npm): publish under scoped name @punitarani/fli (#185)

The unscoped names `fli` and `flights` are already owned by unrelated
accounts on npm, so publishing under either returns 403. Switch to the
author's personal scope `@punitarani/fli`, which is available and
requires no org. `publishConfig.access: public` is already set, so the
scoped package publishes publicly (installable via
`npm install @punitarani/fli`).

- fli-js/package.json: name fli -> @punitarani/fli
- publish-npm.yml: environment url -> .../package/@punitarani/fli
- fli-js/README.md: install command + import examples use the scoped name
