Simplify the Cosmos entrypoint and tighten workspace sidebar sizing

[rushabhcodes]

Summary

This PR removes the dedicated cosmos/ folder by moving the React Cosmos entrypoint into src, and tightens the workspace sidebar sizing so the preview uses stable Tailwind utility classes.

Changes

• move the Cosmos entrypoint from cosmos/main.tsx to src/main.tsx
• update index.html to load /src/main.tsx
• remove the cosmos path from tsconfig.json includes
• replace bracketed Tailwind width and tracking utilities in WorkspaceCodeEditor with equivalent standard utilities

Why

This keeps the repo structure aligned with sibling packages and removes a special-case top-level folder. It also avoids depending on bracketed Tailwind utilities for the workspace sidebar preview.

Impact

• no change to the published package entrypoint or public exports
• no change to the Cosmos-based dev workflow
• simpler project layout for local development

Validation

• bun run typecheck
