add package: pyproject + src

AioProxies: proxy parsing/formatting (aiohttp/camoufox/socks5/url) and
source management (session template with {session} + caller fields,
rotating list, static, from_file). config-free, no module globals,
per-instance rotation, never sys.exits on a missing file. also exported
as ProxyManager / aioproxies. optional [net] extra adds aiohttp
current_ip/reset. src/ multi-module, hatchling, zero core deps.
