CLI usability: pip-installable + default to current directory

[anschmieg]

Summary

This PR adds two small quality-of-life improvements for momoa-cli:

• pip install support — adds a pyproject.toml so the CLI can be installed as a global console script (momoa) via pip install -e .. Also tweaks the agentignore_rules import to work both as a standalone script and as an installed package.
• Default to CWD — when you run momoa "your query" without passing -d or -f, it now automatically operates on the current working directory, saving some keystrokes for frequent use.

Test run

• pip install -e . installs and registers the momoa command
• momoa "prompt" without -d/-f picks up files from CWD
• Explicit -d and -f still work as before
• Running python client-cli/python_cli.py directly still works

Pull request overview

Adds Python packaging and a small CLI UX improvement so momoa-cli can be installed via pip and behaves more naturally when no input paths are provided.

Changes:

• Add pyproject.toml defining a momoa console script and packaging metadata for momoa-cli.
• Update python_cli.py to support both direct execution and package-relative imports, and default file collection to the current working directory when -d/-f are omitted.
• Ignore Python *.egg-info/ artifacts in .gitignore (and add __init__.py to ensure the CLI directory is a package).

Defaulting to uploading the entire current working directory can unintentionally exfiltrate sensitive or very large content (e.g., .env, .git/, node_modules/, virtualenvs), because evaluate_path defaults to include everything when no .agentignore is present and the CLI reads all file contents into memory before chunking. Please add a safety mitigation (e.g., built-in default excludes for common sensitive/huge paths, require confirmation when defaulting to CWD, and/or cap total files/bytes) to reduce accidental leakage and OOM/slow runs.
