fix(packaging): update setup.cfg headers and dependency formatting

[imohitpatel]

This PR addresses minor syntax errors, formatting inconsistencies, and deprecated headers within setup.cfg to ensure standard packaging tools can parse the metadata without issues.

Changes Made

1. Removed Hidden Characters: Cleaned up invisible Unicode non-breaking spaces (\xa0) under requires_dist and ignore keys which could potentially crash strict configuration parsers (such as python's standard configparser).
2. Standardized Dependency Key: Moved the dependency requirements to the standard install_requires under the [options] section, replacing the non-standard requires_dist key under [metadata].
3. Updated Deprecated Header: Replaced the deprecated [wheel] section header with the modern standard [bdist_wheel].

Verification

Checked with standard build tools to verify the config syntax is now clean and valid:

• The file now contains clean spaces for indentation.
• Deprecations have been corrected to align with modern Python packaging guidelines.
