Kudzu 0.7.20 - Computed child collections

Kudzu 0.7.20 accepts a common block-bodied keyed map callback that computes one direct child collection before returning JSX, without executing arbitrary callback code or adding a browser runtime path.

New in 0.7.20

• A keyed map callback may contain one top-level const declaration followed by its final JSX return.
• The const starts from a direct parent-item child property and may use the existing pure filter, direct-property flatMap, or Array.from selector pipeline.
• The computed alias feeds exactly one nested keyed list source.
• The compiler substitutes the proven calculation into the returned JSX and reuses existing selector encoding and keyed ownership.
• Child insertion, reorder, removal, indexes, and DOM identity retain existing nested-list behavior.
• Additional statements, multiple or mixed alias reads, parent capture, mutation, arbitrary calls, and asynchronous callbacks fail during compilation.
• The complete suite passes 107/107 tests.

Boundary

This release supports one direct-child collection const in a block-bodied keyed-map callback. Multiple calculations, aliases used outside one nested keyed list, imported transforms, parent captures, mutation, and async work remain unsupported.
