Bundle with a npm package containing .cljs files

[logseq-cldwalker]

Hi @borkdude. I'm trying to convert https://github.com/logseq/graph-validator to use your new bundling work with a nodejs github action. Ran into this issue / feature request (not sure which). Cheers

Is your feature request related to a problem? Please describe.
I have a nbb{,-logseq} script which depends on cljs files in npm packages.
I tried to bundle with -cp but get this:

$ nbb-logseq -cp node_modules/@logseq/graph-parser/src:node_modules/@logseq/db/src bundle action.cljs -o out.mjs
Error: ENOENT: no such file or directory, open 'logseq/graph_parser/cli.cljs'
...

Since the repro above depends on nbb-logseq, here's a smaller nbb-only repro using the sitefox example:

$ nbb -cp node_modules/@chr15m/sitefox/src bundle webserver.cljs -o out out.mjs
Error: ENOENT: no such file or directory, open 'sitefox/web.cljs'
...

Does -cp just need to be ported over to bundle or is this pulling on something more involved from nbb.core?

Describe the solution you'd like
To be able to bundle a cljs file that depends on cljs files in npm packages

Describe alternatives you've considered
I could copy files out of node_modules to directories where bundle expects them but that seems pretty hacky

Additional context
n/a

Gonna look into it. I think this falls under "enhancement" :)
