Resolve modules relatively when calling `elide run` on file in subdirectory

[franklinfollis]

Summary

elide run path/to/script.ts fails to resolve npm packages when the script is in a subdirectory with its own node_modules.

## Works
$ cd ./my/project/
$ elide run index.ts

# Fails
$ elide run .my/project/index.ts

Fails with:

java.lang.IllegalStateException: Cannot run: Classpaths cannot be calculated without performing `elide install` and `elide build` first. Or, pass `--install` and/or `--build` and Elide will run these for you.

Resolving from where the script is located is already the behavior for Node, Bun, and Deno. elide run should resolve modules relative to where the script is located, not where the command is executed from.
