5727e1d040 Add dynamic heuristic selection for levelwise projection 
Implement weight-based dynamic selection of projection heuristics in
levelwise CAD. The weight function w(p, level) = deg(p, level) estimates
projection complexity, with w(res(a,b)) ≈ w(a) + w(b).

At each level, all three heuristics (biggest_cell, chain, lowest_degree)
are evaluated and the one with minimum estimated resultant weight is
selected. When fewer than 2 root functions exist, the default heuristic
is used since all produce equivalent results.

Add parameter nlsat.lws_dynamic_heuristic (default: true) to enable or
disable dynamic selection. When disabled, the static heuristic from
lws_sector_rel_mode/lws_section_rel_mode is used.

ce0067ca67 Cache partition boundary to avoid repeated algebraic number comparisons 
Store the partition boundary (index of first root > sample) in
relation_E after sorting root functions. Use this cached value
in compute_omit_lc_sector_chain() and compute_omit_lc_section_chain()
instead of recomputing via algebraic number comparisons.

f544dd4ab2 deal with warnings 
@levnach - there are some additional warnings.
You could revert the change to std_vector or use usize() that I added to vector.h. Look at build logs from the pipelines or actions or figure out how to add a continuous AI script to fixup build warnings (I tried a few times earlier on but the features available to do this were not for laymen).
