docs: Motion System v1 + Button gold standard + Component Template + Decision Tree

- Motion System v1 (chapter 5):
  - Motion principles: when to animate, when NOT to animate
  - Duration scale (instant to slower: 0ms to 500ms)
  - Easing functions (linear, in, out, in-out, spring)
  - Component-specific motion: Button, Modal, Drawer, Map, Skeleton,
    Progress, Error/Success
  - Reduced motion support (prefers-reduced-motion)
  - Interruption rules (animations must be interruptible)
  - Error/success animations (shake, checkmark, pulse)

- Button gold standard (chapter 8.3.1):
  - Full specification: purpose, design goal, token dependencies,
    layout, sizes, variants, states, keyboard, touch, accessibility,
    anti-patterns, related components, DDR references
  - Sets the bar for all future component specifications

- COMPONENT_TEMPLATE.md (v1.0, LOCKED):
  - Standard template for all component specifications
  - Sections: purpose, tokens, layout, sizes, variants, states,
    keyboard, touch, accessibility, motion, acceptance criteria,
    anti-patterns, related components, DDR references

- COMPONENT_DECISION_TREE.md (v1.0, LOCKED):
  - Decision trees for: user actions, information display, user input,
    feedback, navigation, Landvex-specific
  - Quick reference table mapping needs to components
  - Prevents invention of unnecessary components

Rationale: Motion before brand (affects every interaction). Button as
reference implementation. Template ensures consistency. Decision tree
guides AI agents and developers to correct component choice.

+# COMPONENT TEMPLATE
+
+**Template for All Component Specifications**

+## Instructions
+
+Copy this template for each new component. Remove sections that do not apply. Add sections that are component-specific.

+**Design Goal:** One sentence describing the ideal user experience.
+
+**Tier:** [1 (Canonical) / 2 (Derived) / 3 (Domain)]
+
+**Inherits From:** [Parent component, or "—" if canonical]
