PR #2221 by jamesf-coder and ksylvan: feat: add OpenCode Zen and Go vendors with session routing
- Added OpenCode Zen and OpenCode Go vendors with support for session routing.
- Simplified session ID handling by replacing UUID generation with
crypto/rand.Textand dropping the UUID dependency. - Preserved existing session IDs and gave preference to named sessions.
- Standardized the User-Agent value for both OpenCode providers to
fabric. - Removed the version detection utilities and their associated tests.
