Research direction

Start in taskuary/cli.py at public_url and _busy, then read test_public_url_rewrites_wildcard_bind in tests/test_config.py. Run python -m pytest -q after adding coverage for the bracketed IPv6 URL and _busy('::1', ) returning False without raising. Done means both IPv6 cases work while the existing behavior remains passing.

Written by the indexing model from the issue text.

Description

bug good first issue 
public_url('::1', 7787)   -> 'http://::1:7787'        # should be http://[::1]:7787
urlsplit(that).port       -> ValueError
_busy('::1', 7787)        -> socket.gaierror          # always opens an IPv4 socket

Where: taskuary/cli.py - public_url and _busy.

Done when an IPv6 host is bracketed in the URL, and _busy works for it (for example socket.create_connection, or the address family from getaddrinfo).

Test - extend test_public_url_rewrites_wildcard_bind in tests/test_config.py with public_url('::1', 7787) == 'http://[::1]:7787', and check _busy('::1', <a free port>) returns False instead of raising.

Getting started: pip install -e ".[dev]", then python -m pytest -q (offline, a few seconds). UI work: cd website && npm ci && npm test. See CONTRIBUTING.md. One small PR with the change and its test is perfect.
