Add a new scanner

Drop a file in netscan/scanners/ — it's picked up automatically on next start.

# netscan/scanners/myscanner.py
from typing import Optional
from netscan import mcp
from netscan.core import add_common, add_targets, base_cmd, run

@mcp.tool()
async def myscanner(targets: Optional[str] = None, ...) -> str:
    """Description shown to Claude."""
    c = base_cmd("myscanner")
    add_targets(c, targets, target_file)
    add_common(c, workers, timeout, delay, resume, nodb)
    return await run(c)
