feat: Project and entrypoint inference

[arnauorriols]

depends on #193 (for the wiring of the entrypoint through the Args)

[satyarohith]

also possible sets are *.tsx & *.jsx

[satyarohith]

LGTM

I would add the additional entrypoints with *.tsx and *.jsx too.

Maybe better to handle a situation where the environment doesn't have git command?

[arnauorriols]

Sorry I don't understand what you mean, can you elaborate?

[magurotuna]

Not all users' environments have git command installed, right? (I believe git is available in 99.9% environments though)
If git command is not in $PATH then new Deno.Command("git").output() throws an error, which we may want to handle.

[arnauorriols]

Ah I see. For some reason I expected it to just output the not found error in stderr. Will handle the error case.

[magurotuna]

Can we do early-return here?

If there's no remote named origin then the git command just fails with non-zero exit code. In this case stdout is empty. So it'd be better to check the exit code before looking at cmd.stdout

[arnauorriols]

Empty stdout is falsy

[arnauorriols]

To clarify, stdout is an empty UInt8Array which is not falsy, but it decodes to an empty string which is falsy. Maybe in this case it's overly confusing. I'll be more explicit
