No-label-float feature

Layer / File(s)	Summary
Public API and frontend label behavior src/main/java/com/flowingcode/vaadin/addons/chipfield/ChipField.java, src/main/resources/META-INF/frontend/paper-chip-input-autocomplete.js, pom.xml	ChipField exposes setNoLabelFloat and isNoLabelFloat. The frontend forwards noLabelFloat to paper-input. The project version changes to 2.8.0-SNAPSHOT.
Demo registration and presentation src/test/java/com/flowingcode/vaadin/addons/chipfield/NoLabelFloatDemo.java, src/test/java/com/flowingcode/vaadin/addons/chipfield/ChipfieldDemoView.java	A routed demo displays ChipField instances with and without floating labels. The demo is registered in ChipfieldDemoView.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: ⚪ Minimal · up to e50d9

The PR adds an opt-in option to keep the floating label from moving while preserving existing behavior by default. No actionable merge-blocking risk remains after normal checks and review.

Code review (low effort) — no findings

Reviewed the noLabelFloat property (Polymer element + paper-input binding), the ChipField accessors, and NoLabelFloatDemo. No correctness or cleanup issues found; the change follows the existing conventions in the repo:

• ChipField.setNoLabelFloat / isNoLabelFloat use the same setProperty(...) / getProperty(name, false) pair as closable, disabled and additionalItems.
• no-label-float$="[[noLabelFloat]]" uses the same $= attribute-binding form as disabled$ / readonly$ / required$. Polymer serializes boolean false to undefined and removes the attribute, so the default behavior is correct.
• NoLabelFloatDemo mirrors ReadonlyDemo / StyledDemo (route prefix, @DemoSource, @SuppressWarnings("serial"), VerticalLayout) and is registered in ChipfieldDemoView.
• The pom.xml 2.8.0-SNAPSHOT hunk only reflects the older merge-base; that bump is already on master.

Non-blocking observation (not a defect in this change): paper-input-container hides the non-floating label based on the input text only, not on the presence of chips, so a non-empty label combined with pre-existing chips can overlay the chip prefix until the user types. The demo sidesteps this by using an empty label and letting the FormLayout form item carry it, and the javadoc describes the behavior accurately, so this appears intentional.
