Polish README

[horn111]

Description

Polishes the README and roadmap so the repo matches the current state of Polymarket UI Kit before grant submission.

Changes include:

• Fixed broken README navigation separators.
• Updated the first-screen positioning to include Combo-aware UI.
• Clarified that the static SVGs are design previews and the live demo is the current source of truth.
• Made npm and hosted registry wording honest: first prerelease and hosted endpoints are planned, while local repo usage works today.
• Added local demo startup instructions.
• Updated the roadmap from 12 to 18 React components.
• Added Combo-aware public market discovery, leg picking, share cards, and intent payloads to the roadmap.

Type of Change

• Bug fix
• New feature
• Breaking change
• Documentation update

Checklist

• README matches the current project state.
• Roadmap reflects the current component count and Combo-aware scope.
• No runtime code changes.
• No claims imply npm or hosted registry are live before release.

Testing

Not run. Documentation-only update.
