fix(ingester): retry get_state on startup DB errors; bump deps + rename behave packages

ingester: wrap bootstrap get_state() in forever-retry loop — MySQL coming
up after the API process killed the ingestion task permanently before it
ever entered _run_loop. Regression test added.

deps: idna 3.13→3.15 (CVE-2026-45409), twisted 26.4.0rc2→26.4.0
(PYSEC-2026-160), pip 26.1→26.1.1 (CVE-2026-3219 resolved upstream),
behave-core/behave-shell renamed from decnet-behave-* and bumped to 0.1.1.
pre-commit hook updated to reflect current ignore list.
