Added deterministic Octave-backed parity tests for core MATLAB PLS/plscmd helpers and non-rotated end-to-end analysis methods (2, 5, 6).
Added deterministic method-4 Octave parity coverage using fixed resampling matrices (permsamp/Tpermsamp and bootsamp/bootsamp_4beh).
Added deterministic methods-3/5 Octave parity coverage with fixed permsamp/bootsamp paths, including permutation/bootstrap output checks.
Added deterministic method-1 Octave parity coverage with fixed permsamp/bootsamp paths, including inference-output checks.
Added deterministic methods-2/6 Octave parity coverage with fixed permutation/bootstrap order matrices, including inference-output checks.
Added support for caller-supplied permutation/bootstrap order matrices in pls_analysis() and wired pass-through to inference internals.
Added generated Octave split-half fixture coverage under tests/testthat/fixtures/matlab/splithalf_result.rds.
Documented intentional correctness divergence for missing-data handling: plsrri treats all non-finite values (NA/NaN/Inf) as missing in pls_xcor() missing-data mode, while legacy MATLAB missnk_* utilities can propagate non-finite output with Inf inputs.
