Missing global pnpm and bun package listing from doctor command.

### Running `doctor` command doesn't output globally installed packages by `bun` or `pnpm`.

#### Output when you have packages installed globally by `bun` or `pnpm`

#### Output when you run `doctor` command.

#### Output when you run `doctor` command should display globally installed packages. like so:
(Haven't fixed the `bun` yet so only `pnpm` packages are sown. But we can do the same thing for bun)

Start at the `doctor` command entry point and trace how globally installed packages are currently discovered and displayed. Reproduce the report with global packages installed through pnpm and bun, then verify that both package lists appear in the doctor output alongside existing results.
