Closes #728

A clipped render whose transformed page exceeds 524,288 pixels on either side now raises pyropdf.LimitError with code clip_page_side. The diagnostic includes the transformed dimensions and the pixel limit. The renderer reads the existing bound from the limit registry. The API reference and rendering guides document the exception.

Acceptance

• The registered code and the 524,288-pixel bound appear in the generated limit table. The issue's 2,384,000 × 1,684,000 pixel reproduction raises LimitError with the expected code.
• The public tests render a clip at the exact bound and check the error class, code and diagnostic with either dimension one pixel over. The clipped output raster's width, height and area tests also pass.

Verification

• python3 tools/check.py --locked python and python3 tools/check.py --locked rust passed on macOS arm64. Python had 8,161 passed and 8 skipped.
• The six focused boundary cases passed. tools/generate_limits.py --check and tools/api_reference.py --check also passed.
