Skip multi-part usernames in project directory names

[nmpowell]

Summary

Previously the

Skip the first part if it looks like a username (before common dirs)

resulted in local multi-part usernames like my.name become my-name and subsequently only my was removed by:

if i == 0 and not found_project:
    # Check if next parts contain common dirs
    remaining = [p.lower() for p in parts[i + 1 :]]
    if any(d in remaining for d in skip_dirs):
        continue

Which resulted in unsightly local paths like name-github-some-project which should really be github-some-project.

This PR:

• Strips the current user's username (with dots converted to dashes) as a prefix when generating display names (and output paths) for local project directories
• Handles multi-part usernames like first.last that get encoded as first-last- in the directory name
• Falls back to skipping the first part if a skip_dir exists later, when the username prefix doesn't match
• Preserves original behavior of skipping all skip_dirs (projects, code, repos, src, dev, work, documents)
• Added tests for multi-part username prefix stripping
