* Refactor debounce counters with direct indexing * Refactor code to use array indexing for debounce_counters * Use global MATRIX_ROW_SHIFTER macro * Refactor debounce algorithm with static allocation * Converted arrays to static allocation * Standardised use of MATRIX_ROWS_PER_HAND for array sizing * Added Doxygen comments for primary debounce functions * Removed debounce_free() * Rewrite sym_defer_pr * Modernise code using sym_defer_pk as template * Format consistency with other current algorithms * Use shorter SPDX-License-Identifier * Remove ChibiOS core memory manager guard * Keep type definition within DEBOUNCE guard * Add change log * Minor optimisation refactor * Pre-calculate row_offset in per-key matrix loops * Add inline compiler hints * Improve readability with blank lines * Limit elapsed time to the maximum debounce value * Apply suggestions from code review Declare counters with "DEBOUNCE_ELAPSED" Co-authored-by: Joel Challis <git@zvecr.com> * Update change log to new breaking change date --------- Co-authored-by: Joel Challis <git@zvecr.com>
