* feat(ghidra): recover signed AArch64 relative jump tables
Generalise the AArch64 relative-table matcher to signed byte/halfword entries, UXTW indexes, byte or LSL #2 offsets, B.CS/B.HS bounds and a CBZ route for zero entries. Cross-check it against Ghidra's own load table when one exists, and add a fixture modelled on the RenderScript blend kernel.
