To simplify debugging, allow passing working dir

This allows running from VSC to WSL directly and pass the target dir to process (since working dir has to be the one with the project).

Simplify --init handling, make it cross-cutting

Fix issue when traversing directories

The missing '/' separator after the base `/contents` uri caused empty results.

Set process output encoding to UTF-8

This enables full unicode in commit change log too.

Optimize retrieval and propagation of X-Sha

Ensure http client is disposed after execution
