fix: oracle format mismatch — convert string entries to dicts, auto-infer checks

Root cause: 130 MCP-unique tasks had oracle_answer.json with string-format
file entries ("sg-evals/repo/path/file.go") instead of dict format
({"repo": ..., "path": ...}). oracle_checks.py crashed with
AttributeError: 'str' object has no attribute 'get'.

Additionally, ALL 211 MCP-unique tasks had 0 evaluation checks because
oracle_check_types was never populated in the selection file.

Fixes:
- hydrate_task_specs.py: add _normalize_file_entry() to convert strings
  to dicts during hydration; auto-infer check types from oracle data
  (files→file_set_match, symbols→symbol_resolution+keyword_presence,
  chain→dependency_chain)
- oracle_checks.py: add _coerce_file_entry() as defensive normalization
  in check_file_set_match() so string entries don't crash
- Re-ran hydration: 209/211 tasks now have evaluation checks
  (2 tasks have genuinely empty oracles, need manual curation)
- Regenerated all 211 oracle_checks.py copies in task dirs
