fix(shared): Use canary tag for 0.x.x package versions

[jacekradko]

Summary

• Fix URL resolution for packages with 0.x.x versions
• When @clerk/ui is at version 0.0.1, getMajorVersion was returning "0", creating invalid CDN URLs like @clerk/ui@0/dist/ui.browser.js
• Now returns "canary" for 0.x.x versions, so URLs resolve to @clerk/ui@canary/dist/ui.browser.js

Test plan

• Added unit tests for 0.x.x version handling
• Verified prerelease tags still work for 0.x.x versions (e.g., 0.0.1-next.0 → next)
• Existing tests pass
• Build passes

Summary by CodeRabbit

• Bug Fixes
  • Version selector now resolves 0.x.x releases to "canary" and correctly maps 0.x prerelease versions to their prerelease tags.
• Tests
  • Added tests covering 0.x.x resolution (including prefixed/whitespace variants) and varied prerelease tag formats.

📝 Walkthrough

Walkthrough

Updated version selection logic and tests: getMajorVersion now maps major version 0 to the string canary instead of returning "0". New tests were added to packages/shared/src/__tests__/versionSelector.spec.ts verifying 0.x.x versions resolve to canary and that 0.x.x prerelease versions resolve to their prerelease tags (e.g., next, alpha, beta, or remain as the full prerelease version when appropriate). A changelog entry .changeset/fix-version-selector-zero.md was added.

I think it's more appropriate for this logic to live in our worker instead.
