The ArgumentHelpText attribute can now be applied to the record type itself
to display help text at the top of the --help output, before field descriptions.
This enables better documentation of command-line argument parsers.
Features:
- Type-level help text appears before argument list
- Multiline help text is supported
- Backward compatible with existing code
- Help text appears in both --help and error messages

Implements support for --no- prefix negation on boolean and flag DU fields
when marked with [<ArgumentNegateWithPrefix>]. This allows both --flag and
--no-flag forms to be accepted, with --no- variants negating the value.
Changes:
- Extend ArgParserGenerator to generate --no- prefix handling
- Add conflict detection for overlapping --no- prefixed arguments
- Update help text to display both forms (e.g., --verbose / --no-verbose)
- Add test examples in ArgParserNegationTests.fs demonstrating:
- Boolean field negation
- Flag DU negation
- Multiple ArgumentLongForm with negation
- Combined features (defaults, help text)
