Use main repo directories for shared dependencies

Simplified the worktree setup to use the main repository's node_modules
and vendor directories directly instead of creating a separate .shared-deps
directory.

Changes:
- Updated conductor-setup.sh to symlink directly to main repo's directories
- Updated CLAUDE.md to reflect the simpler approach
- Symlinks now point to ../../node_modules and ../../vendor

Benefits:
- Simpler setup with no extra directories
- All worktrees share the main repo's dependencies
- No need to add .shared-deps to .gitignore
