Remove the hand-rolled analysis submit path (gitea #83)

b2luigi's AnalysisComputeTask now submits the per-(plot, chunk) jobs, so the
bespoke submit-file generator has nothing left to do:

- giant/analysis/condor.py -> giant/analysis/run.py, dropping SubmitConfig,
  the wrapper/submit-description templates, _job_walltimes and
  _resolve_giant_executable. What stays is the actual logic — prep,
  RunMeta, the rollout-YAML loading, compute_reduced/compute_one and
  merge_one/merge_all — and the module no longer submits anything, hence
  the name.
- `giant analyze submit` is gone; prep / compute-one / merge-one / list /
  render / metrics remain as the single-step primitives the workflow calls.
- tests/test_condor.py -> tests/test_analysis_run.py, minus the
  submit-description cases.

CLAUDE.md and README.md document the workflow package, the new `workflow`
extra, and — for whenever condor-gpu-train-rollout is merged — that its
train-submit/rollout-submit commands are deliberately superseded and must
not be revived.
