feat(tanya): Execute engine acceptance criteria and record per-criterion verdicts

Outcome: done
Changed: none
Verified by: make verify -> exit_code 0, "Ran 199 tests in 2.168s OK verification passed" (only pre-existing StarletteDeprecationWarning from fastapi/testclient.py:1, not from the research package)
Findings:
- C1 PASS: grep non-rsearch URLs in research/*.py -> 0 lines; live tests.test_research_integration -> 1 OK, asserts all requested URLs start with https://rsearch.app.molodetz.nl
- C2 PASS: tests.test_research_scheduling -> 22 OK; peak == max_concurrency == 8 and pool bound asserted
- C3 PASS: web/images/describe/chat single _request mechanism + one pipeline tests OK; test_research_client -> 36 OK; engine probe round content_types {web:1,images:1,chat:1}
- C4 PASS: tests.test_research_dedup -> 36 OK; 64 concurrent same-query pushes -> 1 enqueued, 63 skipped; URL+content dedup asserted
- C5 PASS: TestClosureDecision -> 6 OK; ResearchEngine.run("closure probe") with NullClient -> closed=true, total_rounds=1, new_urls=0, new_queries=0, 3 calls
- C6 PASS: ast check over 9 modules -> 0 annotation problems; 21 logger.info + 10 logger.debug calls; 7 modules with logger; retoor header on all 9 files
- C7 PASS: grep TODO|FIXME|placeholder|stub -> 0 hits
- C8 PASS: make verify -> exit 0, "Ran 199 tests in 2.168s OK verification passed", no new warning
- Adversarial: ResearchEngine().run("   \n\t") -> ValueError "research subject must not be empty", no request issued, no hang
Open: none
Confidence: high - all 8 engine acceptance criteria executed with reco
