Add adaptive flow grid and local layout advisor

[dedsec1911]

Summary

• add AdaptiveFlowGrid and Adaptive.layoutValue for deterministic layouts that respond to viewport width, aspect ratio, and density
• wire the adaptive grid into the Android and Desktop samples and cover its resolver plus Compose behavior with tests
• add an optional local Ollama layout advisor for development-time token suggestions without bundling a model or adding a runtime dependency
• remove unused multiplatform dependencies, keep the JS platform lookup lightweight, and stop tracking machine-local configuration

Why

KitFlow exposes responsive primitives, but consumers still have to hand-build wrapping grids for narrow phones and unusual screen shapes. This adds a small common API for that layout decision while keeping runtime behavior deterministic and offline. The local LLM is deliberately an optional developer tool rather than part of the shipped library.

Impact

• no model, Python code, or Ollama client is packaged with the Kotlin library
• direct published POM dependencies drop from 10 to 6 on Android/Desktop/Wasm and from 12 to 7 on JS
• measured aggregate artifact growth is about 0.58%; the Android AAR grows by 5.6 KB and the Desktop JAR by 4.2 KB
• the new grid uses natural height by default and offers opt-in overflow clipping

Validation

• :shared:desktopTest — 22 tests passed, including resolver and Compose UI coverage
• Android, Desktop, JS, and Wasm shared targets compiled successfully
• Android and Desktop manual samples compiled successfully
• local layout-advisor test suite — 4 tests passed
