chore: update lockfiles to stratum 006363aa (AcceleratingPartialRetarget)

Point stratum-core dependency to marafoundation/stratum branch
vardiff/simulation-framework at commit 006363aa which includes:
- AcceleratingPartialRetarget as production UpdateRule
- EwmaEstimator (reverts SpmRatioEstimator which had a production bug)
- AsymmetricCusumBoundary with tighten_multiplier=3.0

Pin idna_adapter to 1.1.0 to avoid icu_collections 2.2 which requires
Rust 1.86 (Docker image has 1.85.1).
