Add LinearLayout inversion and live matrix visualization with basis calculation

[leeliu103]

This commit implements output-to-input coordinate mapping for LinearLayout visualization by leveraging Triton's basis-based approach:

Core Features:

• Add fromBitMatrix() and invert() methods using binary Gaussian elimination
• Implement output-traversal mode that applies inverted layout to recover input coordinates
• Add live matrix updates: canvas refreshes immediately as user edits matrix
• Simplify tooltip to show input/output coordinates with correct bit widths (log2 of dimension size)
• Add vertical matrix basis calculation display matching Triton's format
• Fix basis column and row ordering to match matrix editor

UI/UX Improvements:

• Add spacing between basis columns from different inputs in tooltip for visual clarity
• Remove text labels from LinearLayout canvas cells (color-coded only) to avoid dimension name mismatch
• Keep text labels for WMMA/MFMA tabs which use canonical dimension names

Performance & Correctness:

• Fix double layout computation: eliminate redundant rebuild when dimension edits trigger matrix-change event
• Align invert()/isInvertible() with Triton's "square and surjective" requirement
• Remove unused columnIndex field from BasisColumnDescriptor

Default parameters: output 16×16, input reg(8) + thread(32) All 115 tests passing.
