The Jacobi, Gauss-Seidel and PageRank demos now print every computed vector component on both the current pin and the upcoming runtime. The solvers retain their original containers and arithmetic. Tests check all three finite components on each named output row instead of matching a number anywhere in the transcript.

The upstream type change is intentional: EigenScript#1093, commit f8745782, changed scalar zeros from list to buffer. Its SPEC documents the breaking change.

Validation: all3 lab programs and all3 vector rows pass on v0.43.0 (a6c50fb) and candidate1c57a1d0; lint17/17 on both. Baseline candidate lab failed on the buffer placeholder. Each of3 reverted display sites fails its named assertion;6 wrong-middle-component controls fail;2 actual-output controls pass; exact restored lab passes. Independent source review found no blockers. Full pinned CI remains the merge gate.

Closes #42.

Materialize a display list for Jacobi, Gauss-Seidel and PageRank, preserving
the numerical solver results and buffer allocation. EigenScript#1093
(f8745782) intentionally changed scalar zeros to numeric buffers.

Closes #42.

Validation: lab 3/3 programs and all three numeric vector rows on v0.43
and runtime candidate1c57a1d0; lint17/17 on both. Baseline candidate lab
red; all3 old-display mutations red; 6 wrong-component controls red;
2 actual-output positive controls and exact restored lab green.
Independent source review found no blockers.

test_lab.sh: PageRank prints <buffer:3> instead of the distribution against EigenScript main (CI green on the v0.43.0 pin)
