Fixes#29637.
OpenCV 5.0 changed vector-backed Mat/OutputArray to true 1D arrays (see
migration guide: 1D and 0D array semantics). This changes HoughLines/
HoughLinesP Python return shape from (N,1,X) to (N,X), breaking the old
indexing pattern used in the tutorial sample.
Tested locally against opencv-python 5.0 — script runs without error,
lines drawn correctly on samples/data/sudoku.png.
Removed obsolete python samples #25268
Clean Samples #25006
This PR removes 36 obsolete python samples from the project, as part of an effort to keep the codebase clean and focused on current best practices. Some of these samples will be updated with latest algorithms or will be combined with other existing samples.
