Accept dotted (module-qualified) type names in parameter annotations

[huyhoang171106]

Summary

The Python parameter inference logic currently misses annotated parameters when the annotation is package-scoped (for example datetime.date, datetime.datetime, datetime.time). This causes --help-notebook to skip otherwise valid parameters declared with PEP-526 style annotations. The root cause is an overly restrictive annotation-matching regex that accepts only a single identifier token for the type.

Pull request overview

This PR fixes Python parameter inference so that PEP-526 style annotations using module-qualified (dotted) type names (e.g., datetime.date) are recognized during PythonTranslator.inspect, which in turn improves parameter discovery for --help-notebook.

Changes:

• Broadened the Python parameter-regex annotation matcher to allow . in annotation tokens.
• Added a regression test ensuring PythonTranslator.inspect parses a dotted annotation correctly.
