Summary

Runtime support for Codelessly/CodelesslyAPI#44, found while rebuilding a jobsite daily log app in the editor. This branch is merged with master. Master's wrap and spacing (#75), dialog presentation and alignment (#76) and its formula functions replace this branch's versions. What this PR still adds:

• Signature nodes
  • Draw a signature by finger, pen or mouse; strokes are written to the bound value and fire changed.
  • Setting the variable redraws the box; read-only boxes only show it.
• Hold to confirm
  • The hold trigger runs its actions once the node has been held for its duration.
  • While held, the node and everything inside it can read ${hold} (0 to 1).
• Dialogs
  • presentCanvas shows full-screen dialogs.
  • Bottom sheets are as wide as the screen and as tall as their content, up to 90% of it (CanvasSizing.sheet), and always sit on the bottom edge.
  • A responsive layout in a dialog picks its layout by the screen width.
• Bound flex
  • A row now reads a child's bound flex when it lays out its Flexibles. Master's binding patched the child's own style, which can't change its share of the row, so bound bars kept equal widths. flex_binding_test.dart covers this.
  • A bound flex of 0 collapses the child.
• Bindings: strokeWeight, and the icon a node shows.
• Formula record helpers: unset, prepend, updateWhere, removeWhere, findIndex and newId. set also takes a list and an index, and indexOf and slice also take text.
• ${hovered} was dropped in favour of the editor's per-node interaction states.

Everything is under ## Unreleased in CHANGELOG.md.

Checks run locally against Codelessly/CodelesslyAPI#44: dart format, flutter analyze --no-pub (no issues) and flutter test (749 tests passing). The merge also fixes two quote lints in master's formula_math_test.dart.

Known Issues

• CI stays red until codelessly_api 6.2.0 is on pub.dev. Master already requires codelessly_api ^6.2.0, which isn't published yet, so dependency resolution fails, including for the example app's web build.

The check job fails at flutter analyze, as expected for this PR. Formatting passes; all 32 analyzer errors are types and fields this PR uses from Codelessly/CodelesslyAPI#44 that the published codelessly_api 6.1.0 doesn't have yet: SignatureNode, TriggerType.hold, TriggerModel.duration, DialogPresentation, and RowColumnNode.wrap/spacing/runSpacing.

This PR can't fix that itself. Once API#44 merges and the API is released, raising codelessly_api to the new version here should turn CI green. Locally, against the API branch, flutter analyze reports no issues and flutter test passes all 667 tests.
