Rename og-local CLI to veil

[adambalogh]

Summary

Rename the command-line tool from og-local to veil throughout the codebase, including documentation, user-facing messages, and configuration.

Key Changes

• Updated the CLI command entry point in pyproject.toml from og-local to veil
• Renamed all references in user-facing documentation (README.md) from og-local to veil
• Updated all help text, error messages, and instructional output in the CLI module to reference veil instead of og-local
• Updated docstrings and comments throughout the codebase to reflect the new command name
• Updated test assertions to expect the new command name in error messages
• Updated the Makefile to use the new command name

Notable Details

• The Python package name (og_local) and internal module structure remain unchanged
• All functionality remains identical; this is purely a user-facing naming change
• Error messages and help text now consistently guide users to use veil for all operations (login, stop, status, update, logout, etc.)
• The change affects approximately 40+ references across 8 files
