[wgordon17]

Summary

• Rejects lengths outside the CUID2 specification range 2..32 with ValueError in the library and exit code 2 in the CLI, and defaults and clamps is_cuid max_length to 32.
• Removes MAXIMUM_LENGTH (98), the FutureWarning machinery, _console_main and _show_cli_warning; the console script and python -m cuid2 call cuid2.cli:main directly.
• Updates tests, README, and the CHANGELOG Unreleased section, including an upgrade note for callers using lengths above 32.
