Release train for 0.6.0:

• Bump the tauargus-engine pin to 6e295c5 (same engine master commit as the pytauargus 0.6.0 train: the 0.5.7 train plus PR chore(deps): update actions/setup-node action to v4 - autoclosed InseeFrLab/rtauargus#21 no-op cost/bounds skip and PR régler issue pkgdown InseeFrLab/rtauargus#22 csp pin and binding version).
• DESCRIPTION is unchanged on disk (kept 1:1 with INSEE upstream); the release version lives on the tag.
