fix: align package version and CDN links for npm/CDN distribution

[Copilot]

Summary

package.json version was stuck at 1.0.0 while the git tag and CHANGELOG were already at 1.0.2 — npm publishes whatever package.json says, so the package would have shipped as the wrong version. CDN links across README and wiki contained either @<version> placeholders or stale @1.0.0 references.

Scope

• bug fix
• feature
• docs
• tests
• release/chore

Validation

npm run pack:dry

pack:dry confirms the tarball now reports interactive-surface-css@1.0.2.

API and Behavior Impact

• no public API changes
• class API changed
• token contract changed
• accessibility behavior changed
• motion behavior changed
• browser behavior changed

Documentation

• README updated (if needed)
• wiki updated (if needed)
• CHANGELOG updated (if needed)

Notes

• README.md: CDN block was also incorrectly nested inside the Webpack numbered list — extracted it as its own top-level section.
• All @<version> and @1.0.0 CDN references normalized to @1.0.2 across README.md, wiki/Getting-Started.md, and wiki/Installation-and-Usage.md.
• No logic or stylesheet changes; purely version/metadata alignment.
