chore(release): v0.0.9

[thomaspinder]

Version bump for v0.0.9. pyproject.toml + uv.lock only, matching the v0.0.8 release commit (99ee00c).

Ships the 27 commits on main since v0.0.8. Release notes are drafted separately; three behaviour-changing fixes lead them:

• fix(identification): return the ordered Cholesky factor in data row order #208 — custom Cholesky(ordering=...) now returns rows in data order. Previously mislabelled, so those IRF/FEVD/HD numbers change. Identity orderings byte-identical.
• fix(spec): scale the B_exog prior to the data instead of pinning sigma=1 #237 — the B_exog prior now scales to the regressor, so every NUTS-with-exog posterior changes. Constant exog columns rejected.
• Multivariate SV forecast drops the per-variable log-vol level mu_i #241 — multivariate SV forecast bands change (the per-variable log-vol level was dropped from the forecast).

Blocked on nothing; #268 (the #241 fix) is merged.
