refactor(eval): consolidate to single provider, remove obsolete config variants

- promptfooconfig.yaml: replace three exec providers (default/progressive/
  no-memory) with a single exec:./bin/eval-runner; remove eval-matrix
  references; latency assertion is now a graded quality signal (score
  degrades linearly 30–90 s) instead of a hard pass/fail gate
- Remove eval/cases/progressive_disclosure.yaml (covered by meta_tools.yaml)
- Remove eval/configs/no-memory.json and eval/configs/progressive.json
  (single-profile eval; overlay configs no longer needed)
- Remove eval/promptfooconfig-default.yaml (merged into promptfooconfig.yaml)
- eval/go_evals/eval_test.go: remove test cases for deleted config files
- error_recovery.yaml: add security leak detection; partial-pass for safe
  fallback responses
- reasoning.yaml: add read_file to output-dependency assertion; add year
  value assertion; partial-pass for meaningful non-default responses
