Intended to be used directly and/or from skills in an agent. Usage is `./scripts/worktree.sh [--compiler] [--claude] <name>`. The script: * Checks that ./worktrees is in gitignore * Checks the named worktree does not exist yet * Creates the named worktree in ./worktrees/ * Installs deps * cds into the worktree (optionally the compiler dir if `--compiler`) * optionally runs claude in the worktree if `--claude`
