deps(deps): bump taffy from 0.7.7 to 0.13.0

[dependabot]

Bumps taffy from 0.7.7 to 0.13.0.

Release notes

Sourced from taffy's releases.

v0.13.0

The MSRV for this release is 1.71.

Added

• Support for the self-start and self-end alignment keywords (AlignItems::SELF_START/SELF_END and safe variants). These resolve against the direction of the item itself rather than that of its container, so they only differ from start/end when the item's direction differs from its container's. Supported for align-self/align-items and justify-self/justify-items on both in-flow and absolutely positioned Flexbox and Grid items (#1074)

• Support for display: flow-root. The new Display::FlowRoot variant lays out children using the block layout algorithm but always establishes a new block formatting context (its margins do not collapse with those of its children, it contains its own floats, and it avoids external floats)

Changed

• Numeric style helpers (length, percent, fr, flex) now accept Input: Into<f64> instead of Input: Into<f32>. This allows bare float literals such as length(800.0) to be used without triggering the float_literal_f32_fallback future-compatibility lint, while widening the set of accepted numeric input types (#974)
• Grid: grid_template_areas is now Option<GridTemplateAreas<S>>, where the new GridTemplateAreas struct includes row_count/column_count fields. This allows templates containing unnamed (.) cells beyond the extents of the named areas (e.g. grid-template-areas: "a .") to be represented.
• Block/float: BlockContext::place_floated_box takes an additional adjoins_unresolved_strut: bool parameter indicating whether the float is being placed while the position of the current margin-collapse strut is still unresolved

Fixed

A large number of miscelaneous bug fixes are included in this release:

• Flexbox: clamp the flex base size, automatic minimum size and hypothetical main/cross sizes with min/max sizes transferred through the aspect ratio, instead of baking them into the item's used min/max sizes (#989)
• Flexbox: resolve justify-content: start/end and align-self: start/end/self-start/self-end as writing-mode relative (rather than flex-relative) in the static position of absolutely positioned children; use the flex-relative start for justify-content: space-between/normal, and a fallback of start for align-self: baseline (#1072)
• Flexbox: only let auto margins on absolutely positioned children absorb free space when the box is inset-constrained in that axis; otherwise they resolve to zero per CSS2 §10.3.7/§10.6.4 (#1072)
• Grid: jump the auto-placement search past entire colliding occupied intervals rather than advancing one track at a time (#1038)
• Grid: resolve the grid lines used by absolutely positioned items to the edges of the adjacent tracks, so that free space distributed by align-content/justify-content is not included in the abspos grid area (#1071)
• Grid: exclude absolutely positioned children from the implicit grid size estimate, as they do not take part in grid placement and must not create implicit tracks. Previously their out-of-range lines resolved to phantom implicit tracks instead of being treated as auto (#1075)
• Grid: align an empty grid (one whose tracks have all collapsed) within its container, rather than always placing it at the start (#1078)
• Grid: only distribute space "beyond limits" to tracks whose max track sizing function is max-content (or fit-content()) (#1033)
• Grid: don't clamp an explicitly specified preferred or minimum size by the spanned tracks' fixed max track sizing functions when computing an item's minimum contribution (#1022)
• Grid: ignore the tracks' growth limits when distributing an item's intrinsic size contribution "beyond limits" (#1022)
• Grid: convert the container's min/max size to a content-box size before using it in the track sizing algorithm (#1023)
• Grid: compute the flex factor sum over only the spanned tracks eligible to receive space when distributing intrinsic size contributions to flexible tracks (#1019)
• Grid: don't grow tracks past their growth limits when distributing free space to multiple tracks with asymmetric limits (#1001)
• Block/Grid: measure Layout::content_size from the container's padding-box origin and include the container's own end-side padding, matching Flexbox and browser scrollWidth/scrollHeight semantics. Grid items in tracks that overflow the container now also contribute their position within the container, not just their own size (#1051)
• Block: don't stretch-size replaced elements; an auto width now resolves to the intrinsic size (#1002)
• Block: don't let boxes that establish an independent formatting context overlap floats: they narrow to fit beside the float, or move down below it if they don't fit (#991)
• Block: detect floats placed by the subtree of a preceding in-flow sibling, not just floats among direct siblings, when placing a box that establishes an independent formatting context (#1049)
• Block: apply a negative margin as usual on a BFC root's float-free side, instead of clamping it to the containing block edge (#1061)
• Block: compute clearance from the hypothetical position of the cleared element (including its collapsed top margin), supporting negative clearance (#1042)
• Block: prevent the cleared element's top margin from collapsing with preceding margins and with the parent's top margin (#1043)
• Block: force clearance for floats placed while the position of the enclosing margin-collapse strut is unresolved, and position such floats including the pending collapsible margins (#1046)
• Block: collapse the top and bottom margins of a self-collapsing element with clearance with each other and apply them inside the parent, rather than collapsing them with the parent's bottom margin (#1044)
• Block/float: treat clear as a no-op when no float has been placed on the relevant side(s) (#1041)
• Block: allow elements containing only floated children to be collapsed through (#1040)
• Block/float: record zero-width floats in the float context, so their edge acts as an obstacle for boxes establishing an independent formatting context (#1062)
• Block/float: a float establishes a new block formatting context, so its margins no longer collapse with the margins of its children (#1065)
• Block/float: honour CSS2 §9.5.1 rules 3 & 7 when placing floats: a float unconstrained by other floats may overflow its containing block, but one placed beside another float may not (#1064)
• Block/float: apply CSS2 §9.5.1 rule 5 (float ceiling) and clear past zero-sized floats, which occupy no float segment and so were previously ignored when positioning later floats and cleared elements (#1056)
• Block/float: sum float contributions when computing a float container's intrinsic width under definite available space (clamped between the widest single float and the available width), instead of dropping them entirely (#1055)

[proggeramlug]

Validated locally on macOS: this does not compile. cargo check --workspace --all-targets
(host-compatible scope) is green on origin/main and fails with 30 errors on this branch,
all in crates/perry-runtime/src/yoga.rs. This is a jump across six 0.x releases
(0.7.7 -> 0.13.0), each of which may break API, and no call sites were adapted.

Two independent classes of breakage:

1. The alignment enums were restructured. JustifyContent now resolves to
AlignContent, whose variant set no longer carries the Flex* names:

error[E0599]: no associated function or constant named `FlexStart` found for struct `AlignContent`
   --> crates/perry-runtime/src/yoga.rs:243:30
    | 0 => JustifyContent::FlexStart,

...and the same for Center, FlexEnd, SpaceBetween, and the rest — the bulk of the 30.

2. A thread-safety regression that is not a mechanical rename:

error[E0277]: `*const ()` cannot be sent between threads safely
   --> crates/perry-runtime/src/yoga.rs:118:20
    | static YOGA_NODES: Mutex<Option<HashMap<u32, YogaNode>>> = Mutex::new(None);

The new node type holds a *const (), so it is no longer Send, and the existing global
Mutex<HashMap<u32, YogaNode>> cannot hold it. That one needs a design decision about how
layout nodes are owned across threads, not a find-and-replace.

Leaving this open. Given the size of the jump, stepping through intermediate taffy versions
would probably be easier to review than one 0.7 -> 0.13 port.
