Upgrade taffy for last-baseline support

[nicoburns]

Summary

Bumps taffy to the tip of taffy#1113 (bb30dbf2, top of the stacked series #1110 → #1111 → #1113, which includes latest taffy main) and adapts Blitz to the new last-baseline APIs:

• Inline layout now reports both first and last Parley line baselines via LayoutOutput::baselines: Baselines { first, last } (previously only the first, via Baselines::from_first).
• stylo::AlignFlags::LAST_BASELINE now maps to the real taffy::AlignItems::LAST_BASELINE instead of falling back to END.

Rebased on main, which already includes the Baselines type and scrollable_overflow_rect migrations (#733), so the diff is now just the rev bump plus the two behavioral changes above.

Should merge only after the taffy stack lands; the rev should ideally then be bumped to the merge commit.
