chore: ignore Claude Code worktrees

[qnbs]

What

One line: git ignores .claude/worktrees/.

Why

.claude/worktrees/ holds full checkouts of this repo, inside the repo. An unqualified git add -A in the main checkout therefore stages a worktree as an embedded git repository and commits a bare gitlink instead of the actual change:

warning: adding embedded git repository: .claude/worktrees/pr413-cc
hint: You've added another git repository inside your current repository.

This happened while working on #413: the resulting commit contained nothing but .claude/worktrees/pr413-cc | 1 + and none of the real changes. It was reverted non-destructively, but the trap is open to anyone using Claude Code on this repo.

Scope

Deliberately limited to the worktrees/ subdirectory, so checked-in .claude configuration (settings.json, agents, skills) stays tracked. Verified:

$ git check-ignore -v .claude/worktrees/foo
.gitignore:55:.claude/worktrees/   .claude/worktrees/foo
$ git check-ignore -v .claude/settings.json
(no match — correct)
