chore(deps): update dependency tenacity to v9.1.4

-## Large sources can OOM-kill the pod
-
-On 2026-07-10 the pod was OOMKilled (memory limit was 1Gi) mid-research: a
-batch of 20 concurrent sources hit a 98k-word document plus several large PDFs
-at once, and pdfplumber's parse spiked RAM past the limit. The in-memory
-research task died with the pod and its session sat in `running` forever.
-
-Mitigations now in place:
-
-- Memory limit raised to 2Gi (`k8s-manifests/researchowl/deployment.yaml`).
-- PDFs capped at 15MB (was 50MB), checked both via Content-Length and actual
-  body size; pdfplumber runs in `run_in_executor` (it is sync + CPU-heavy and
-  also froze the event loop, same class of bug as DDGS) and flushes its page
-  cache per page.
-- Extracted content is truncated to `max_content_length` (300k chars) before
-  hitting `source_contents`.
-- On startup the bot marks orphaned `running` sessions as `interrupted`.
-
-If a research still dies, the scraped sources survive in the DB: `/process`
-re-chunks and scores them without re-scraping.
