CLAUDE: manifest-like tests top - cases.list + run_cases.sh (Andrey's design), de-hardwire test defaults

The scene-sequence .list is the human single source of truth (SET header +
body lines selected by uncommenting; commented lines document the setup).
The tests now follow the SAME convention one level up:

- cases.list: SET header (listFile, version - the version deliberately kept
  out of the scene list, mirroring CORRECTION_PARAMETERS.x3dModelVersion vs
  .sourceSequencesList) + case lines selected by uncommenting; commented
  cases stay as documentation. gen lines map synthetic cases to generators.
- run_cases.sh: resolves ${MODEL} through the scene list's SET
  rootDirectory/x3dDirectory + its UNCOMMENTED sequence lines + the version
  (the *-CENTER dir carries the DERIVED center timestamp -> matched as the
  smallest center ts >= the sequence's first-scene ts containing <version>/);
  -x <corr-xml> reads sourceSequencesList/x3dModelVersion directly = the
  same two sources that drive the Java run. No args = all uncommented cases;
  named cases run even when commented; missing synthetic data triggers the
  generator.
- test_proc_consolidate: hardwired absolute case/repo paths -> standard
  --data/--src/--devrt interface (legacy positional kept).
- test_pose_corr_jna: srcdir default de-hardwired (repo-relative 'src').

Verified live: ./run_cases.sh ALL PASS (pose_corr real-scene tol-0 resolved
through the list+version, 4 synthetic cases); named-commented case
avg_td_oob_jna PASS bit-exact via the new interface; gen-on-missing works.
