textual-autocomplete breaks textual-0.12+

[stragulus]

Reproduce:

python3 -mvenv python
source python/bin/activate
pip install textual==0.12.1
python git/textual/examples/calculator.py # it works!
pip install textual-autocomplete
python git/textual/examples/calculator.py # sad face

Looks like it may have broken all widget with the new context manager feature?

Oh my. The issue is, if you manually pip install textual-autocomplete it will DOWNGRADE the existing installed textual package. Reading some more that is apparently a contentious issue with how pip is supposed to handle dependency management. Worked around it by strictly using a requirements.txt file but if this is supposed to work with 0.11+, maybe it should be instrumented to specify that as a minimum requirement so it won't attempt to downgrade existing installs?

With the pace of new Textual releases, I totally understand the problem trying to keep this library compatible.

But this sentence in the README is a bit misleading given the caret requirements in pyproject.toml:

textual-autocomplete supports Textual version 0.11.0 and above.

@darrenburns Is there any chance of an auto-complete feature being added to Textual at some point?
