swaitsandClaude Opus 4.7 2b453464e7 refactor(compare): realign + sort tables, add combinatorial problems
The terminal output was misaligned: headers and data were right-aligned
with hardcoded column widths and separator lengths, and the mean ± std
cells contained the non-ASCII `±` (plus `ε`, `↑`, `↓`) -- on any terminal
that renders those at a non-1 column width the columns drift, and the
hardcoded `-`.repeat(n) separators didn't match the real table width
anyway.

Changes:
- New `print_table` helper: column widths derived from the actual cell
  contents (header + every row), separator length computed to match.
- All table cells are now ASCII: `+/-` instead of `±`, `eps-MOEA`
  instead of `ε-MOEA`, arrows dropped from headers.
- Every table is sorted best-first by its primary quality metric.
- Added three combinatorial / sequencing problems with their own
  (permutation- / bitstring-native) algorithm rosters: a convex-position
  ring TSP (known optimum), FT06 job-shop makespan (known optimum 55),
  and a bi-objective 0/1 knapsack scored by hypervolume.
- Expanded every problem's preamble: what it is, why it's hard, and the
  best-known / optimal result.
- Regenerated examples/compare-results.md to match.

Continuous-problem quality metrics are unchanged (bit-identical to prior
snapshots); only ms columns and row order move.
