build(deps): bump taffy from 0.6.3 to 0.14.0

[dependabot]

Bumps taffy from 0.6.3 to 0.14.0.

Release notes

Sourced from taffy's releases.

v0.14.0

The MSRV for this release is 1.71.

Support for CSS sizing keywords (#1099, #1103)

The width, height and flex-basis properties now support min-content, max-content, fit-content, fit-content(), and stretch keywords. flex-basis additionally supports the content keyword. The min-width/max-width (and height) properties have been switched to use LengthPercentageAuto rather than Dimension, as they do not yet support these keywords.

Support for flex-wrap: balance (#1105)

Taffy now supports flex-wrap: balance and flex-line-count from CSS Flexbox Level 2, behind the default flexbox_balance feature.

See Balancing Text in CSS: The Flex-Wrap Last Row Problem for an explainer.

Partial support for CSS containment (#1128)

The layout effects of contain: layout, contain: paint, and contain: content are now supported, including independent formatting contexts, baseline suppression, and overflow containment. contain: size is not yet supported.

Expanded detailed grid information (#1131, #1134, #1135, #1136, #1137)

• DetailedGridTracksInfo's gutters and sizes fields are replaced by a single positions vec. positions contains the offset of every grid line in the implicit grid. This allows it to account for offsets introduce by content-alignment. And also allows for O(1) access to grid area sizes.
• All data in DetailedGridTracksInfo is now stored in logical order (so right-to-left for direction: rtl grids)
• Added DetailedGridInfo::resolve_absolute_grid_area which can resolve a grid area for an item given it's position styles. This is useful for positioning hoisted absolutely positioned boxes relative to a grid containing block.
• Added grid_template_rows and grid_template_columns methods which serialize those properties into a string according to the CSS standard.

Caching changes

Caching logic is now more correct (#1010, #1155)

Changed

• Tagged-pointer style types now have expand() methods that expose their values as plain enums (#1129).
• Layout::content_size is now scrollable_overflow_rect: Rect<f32>. Its right and bottom fields replace the old width and height values; scroll_width() and scroll_height() are unchanged (#1118).
• LayoutOutput::first_baselines is now baselines: Baselines, with first and last baseline fields (#1107).
• Style::min_size and max_size now use LengthPercentageAuto rather than Dimension (#1099).
• compute_layout_with_measure now passes a LayoutInput and returns LayoutOutput; call compute_leaf_layout explicitly to preserve the old leaf-measurement behaviour (#1091).
• Block and Flexbox no longer measure absolutely positioned children whose dimensions are already known (#1120).
• CacheTree::cache_get and Cache::get now take &mut self, and the measure cache uses second-chance (clock) eviction (#1010).

Fixed

• Cache: prevent axis-specific measurements from being reused for the wrong axis and avoid caching margin-collapse metadata (#1010).
• Flexbox: fix intrinsic sizing with negative margins and zero flex bases (#1152).
• Flexbox: apply inherent style sizing on top of content-size measurements (#1155).
• Flexbox: transfer definite stretched cross sizes through aspect ratios when calculating flex base sizes (#1155).
• Block/float: account for clear when computing the intrinsic width of floats (#1150).
• Flexbox: generate container baselines from the visually startmost line or item in reverse layouts (#1127).

[echobt]

Pushed c5f9ebf to repair the Taffy 0.14.0 migration. Updated compact dimension constructors, alignment keywords, and min/max size conversion. Importing unsupported CSS dimensions now returns UnsupportedDimension through TryFrom instead of silently changing sizing; this API change is documented.

Local validation passed: formatting, workspace Clippy, the full CI TUI package test set, seven new compatibility/buffer tests (40×12 and 120×40, including resize back), readiness script tests, source policy against base 3c06750, release-age policy, and CLI version consistency. Reviewed the diff for security and product-facing errors; no secrets or sandbox/network policy changes.

Fresh CI is required before merge. Full workspace tests, audit, generated contracts, local QA, and coverage remain CI gates. This PR has not been merged.
