Constrain package Python support to 3.11/3.12 to avoid Fedora 3.13 install failures

[Copilot]

pip install microbots fails on Fedora 42 because the default Python is 3.13 while the package pins dependencies (notably numpy==1.26.4) that do not provide compatible wheels for cp313. This change makes compatibility explicit at package resolution time instead of failing later during build.

• Packaging metadata

  • Updated pyproject.toml to gate installable versions:
    • requires-python = ">=3.11,<3.13"
  • Added explicit Python 3.12 classifier (alongside 3.11) to reflect supported runtime targets.

• Documentation alignment

  • Updated docs/copilot-bot.md prerequisites to state support for Python 3.11/3.12 and explicitly call out that Python 3.13 is not currently supported.
