Summary

Move URL normalization logic to the shared package to eliminate duplication across both tools.

Current State

URL normalization is implemented in 3 places:

• tools/jtk/internal/config/config.go - NormalizeURL() (lines 137-147)
• tools/jtk/api/client.go - hasScheme(), trimTrailingSlash() (lines 70-80)
• tools/cfl/internal/config/config.go - NormalizeURL() (lines 44-50)

Proposed Changes

1. Create shared/url/url.go with NormalizeURL() function
2. Update both tools to import from shared
3. Remove duplicate implementations

Impact
