Claude Code's CWD is always the worktree root, so all script
invocations work with plain relative paths (db/connectors/ticket,
db/connectors/qdrant-search, etc.). The REPO_ROOT environment
variable and its settings.local.json definitions are no longer needed.
Updated: CLAUDE.md, all skill files, qatux agent file.
The settings.local.json env sections were also removed across all
9 worktrees (non-git files, edited directly).
