paper review session 5: entries 41-50 (MinimumMaximalMatching–MinimumSetCovering)

- MinimumMaximalMatching: add @xiao2014 citation, O*(1.3160^n) complexity
- PartitionIntoPathsOfLength2: upgrade canonical example from trivial
  6-vertex (two disjoint paths) to 9-vertex 3×3 grid with 12 edges and
  10 distinct valid groupings; add figure, pred commands, fixture
- MinimumSumMulticenter: replace prose citations with @karivhakimi1979,
  @cohenaddad2022
- MinMaxMulticenter: replace prose citations with @karivhakimi1979,
  @hochbaumshmoys1985, @hsunemhauser1979; add per-vertex distances
- MultipleCopyFileAllocation: upgrade degenerate canonical example
  (all vertices host copies) to path P_6 with varied usage/storage
  showing storage-vs-access tradeoff; enrich background with CDN,
  database replication, UFL connection
