Add infrastructure for running Claude and Codex agents in parallel
without conflicts, using isolated git worktrees and shared Docker
dependencies.
Changes:
- Add agent-worktrees and agent-sync Makefile targets
- Pin Docker Compose project names to enable worktree isolation
- Add setup-agent-worktrees.sh script for creating parallel worktrees
- Add sync-agent-integration.sh script for merging agent branches
- Document parallel workflow in 13-agent-parallel-workflow.md
- Update dev-workflow.md with worktree usage guide
Benefits:
- Prevents agents from overwriting each other's work
- Shares dependency containers across worktrees (Postgres/Redis/MinIO)
- Reserves localhost:3000 for integration verification only
- Provides clear merge and recovery procedures
- Add sticky header with LanguageSwitcher and UserMenu to landing page
- Update token dialog and i18n translations
- Fix dev process script and compose release config
- Remove stale skillhub submodule reference
