build(pyproject): adopt PEP 639 license metadata

[njzjz-bot]

Problem

• Several packages still use deprecated table-based project.license metadata.
• PEP 639 standardizes SPDX license plus license-files.

Change

• Replace deprecated project.license = {file/text = ...} with an SPDX expression.
• Add project.license-files.
• Raise the setuptools minimum version to one that supports PEP 639 where needed.
• Remove legacy License :: classifiers superseded by the SPDX expression.

Notes

• This change is metadata-only and does not alter runtime behavior.

Summary by CodeRabbit

• Chores
  • Updated build system dependencies to require setuptools version 77.0.3 or later.
  • Standardized license declaration to use industry-standard SPDX format for improved clarity and compliance tracking.
