fix: Backport macOS specific ver reqs

[erichare]

This pull request updates the dependency configuration in pyproject.toml to improve compatibility with different platforms, especially addressing issues for macOS on x86_64 architecture. The main changes involve conditional dependencies for certain packages and the introduction of a new core package.

Dependency updates and platform-specific adjustments:

• Replaced the unconditional docling dependency with docling-core for all platforms, and made docling conditional so it is only installed on platforms other than macOS x86_64.
• Made easyocr and opencv-python dependencies conditional so they are not installed on macOS x86_64, improving compatibility for that platform.

Minor changes:

• Added a trailing comma to the python-pptx override dependency for consistency.

Summary by CodeRabbit

• Bug Fixes

  • Improved cross-platform installation reliability, especially on macOS (Intel), by refining platform-specific dependency rules.

• Chores

  • Updated core document-processing dependency and aligned related libraries.
  • Applied platform-conditional installs to reduce download size and avoid unnecessary packages on macOS (Intel).
  • Maintained existing dependencies without functional changes.
  • Minor formatting tidy-up in dependency configuration.

Walkthrough

Updates dependency declarations in pyproject.toml: replaces docling with docling-core and restores platform-conditional markers for docling, easyocr, and opencv-python. Keeps other dependencies unchanged. Adds a trailing comma in the python-pptx override section.

Pre-merge checks and finishing touches

❌ Failed checks (1 error, 3 inconclusive)

Check name	Status	Explanation	Resolution
Test Coverage For New Implementations	❌ Error	The PR modifies only dependency declarations without touching any test files. Because it is a bug fix (noted by the “fix:” prefix) and the custom check requires regression tests for bug fixes, the absence of any new or updated tests means the requirement is not met.	Add regression tests that verify the dependency conditions on macOS x86_64, for example by simulating installation or import failures on that platform, to cover the backported version requirements.
Test Quality And Coverage	❓ Inconclusive
Test File Naming And Structure	❓ Inconclusive
Excessive Mock Usage Warning	❓ Inconclusive
